I just started learning about Python (on macOS Mojave). I downloaded the latest version of Python and wanted to download software libraries like pandas.
So firstly I downloaded pip like that: sudo easy_install pip
Then I installed pandas using pip, however pandas location is: Requirement already satisfied: pandas in ./Library/Python/2.7/lib/python/site-packages (0.24.2)
However, my Pythons location is:
Location of Python 3.8.2:
'/Library/Frameworks/Python.framework/Versions/3.8/bin/python3'
Also when I try importing pandas in the python command I get this:
ModuleNotFoundError: No module named 'pandas'
Therefore, it seems that pip has installed pandas to the old version of Python. How can I fix that? Or is that even the problem? Again I am totally new to this and I don't come from a cs background. Please help.
You might have both pip and pip3 installed, where the first is used for python 2.7 and the second for python 3.8.2
pip3 install pandas
You need to add pip to your terminal's commands. In the meantime, you could do this:
python -m pip install pandas
Note that that will only work if when you run python -V, you get python 3.8.2.
I am new to python and I am trying to make a simple stock market program using pandas to import the data. I have installed Anaconda which said that it installed pandas along with it, as well as Python 2.7. I use PyCharm as my IDE. When I run:
import pandas as pd
from pandas_datareader import data
I receive the error message
import pandas as pd
ImportError: No module named pandas
I am not sure why it is giving me this error message so any help would be greatly appreciated
When entering the command to run your file, make sure you specify which version of python you're using. For example, instead of python filename.py, use python3 filename.py or python2 filename.py
Try to install it using sudo ...
sudo pip3 install pandas
for ubuntu ... it worked got me. pip or pip3 .. as per your requirement.
You need to pip install pandas and things will work.
Your issue is that pandas is not installed locally on your computer. Luckily, this is a simple task to accomplish by opening up either a Terminal or Command Prompt (depending on your OS), and typing in the command pip install pandas. This will install pandas and you will be good to go!
The issue is that Anaconda installs a Python version of its own, and likely the Python version is Python 3. When you use PyCharm IDE as your editor, you are using another version of Python (Python2). For my Mac, Anaconda's Python is installed under /anaconda3/bin and my default Python is installed under /usr/bin/python.
I recommend you either config PyCharm to use Anaconda's Python, or use Anaconda's Jupyter your project. Jupyter is arguably a stronger tool considering that you are doing data analytics task.
Also, for Anaconda's python, you shoud use conda install pandas instead of pip install pandas to install additional packages. This is not necessary this time since it's already installed.
Since yesterday I've had this error when I try to import packages on anaconda :
ImportError: Missing required dependencies ['numpy']
I have tried un-installing Anaconda and Python, switching to Python 2.7 but nothing works it's still the same error, here is the code I get :
Any help is really appreciated thanks !
I had this same issue immediately after upgrading pandas to 0.19.2. I fixed it with the following install/uninstall sequence from the windows cmd line:
pip uninstall pandas -y
pip uninstall numpy -y
pip install pandas
pip install numpy
This also broke my matplotlib install so I uninstalled/installed that as well.
Very odd behavior for a seemingly routine upgrade.
What happens if you try to import numpy?
Have you tried'
pip install --upgrade numpy
pip install --upgrade pandas
I had to install this other package:
sudo apt-get install libatlas-base-dev
Seems like it is a dependency for numpy but the pip or apt-get don't install it automatically for whatever reason.
I had this problem with last version of numpy 1.16.x
Problem resolved with
python3 -m pip uninstall numpy
python3 -m pip install numpy==1.14.0
Did you install miniconda and pandas without dependencies?
Try installing numpy first with conda install numpy or pip install numpy.
If you're on Windows you can get pre-compiled versions of most libraries that require compilation from here.
On Windows 10 Anaconda3-5.3.0-Windows-x86_64 I had the Missing required dependencies ['numpy'] error when running scripts as so, %HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe pandas_script_foo.py.
In my case the error was caused by missing Anaconda package PATH definitions when running Anaconda python.exe in a windows cmd.exe session. The numpy package is not missing. It just can't be found on the PATH.
The Anaconda installation includes windows shortcuts that give examples of configuring the PATH per script run. See the shortcuts in the %HOMEPATH%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit) directory for examples.
See the %HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py script to see how Anaconda configures PATH.
Below is an example windows BAT file that calls cwp.py to setup PATH, and then run a python script. Its a copy of the commands the Anaconda jupyter-lab shortcut executes.
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3 ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\Scripts\jupyter-lab-script.py
If you need to execute python scripts on Anaconda with the conveniance of running a BAT file, the above BAT file example should do the trick.
The data manipulation capabilities of pandas are built on top of the numpy library. In a way, numpy is a dependency of the pandas library. If you want to use pandas, you have to make sure you also have numpy. When you install pandas using pip, it automatically installs numpy. If it doesn't, try the following
pip install -U numpy pandas
For conda
conda install numpy pandas
I also faced the same issue. It happened to me after I upgraded my numpy library.
It was resolved in my case by upgrading my pandas library as well after upgrading my numpy library using the below command:
pip install --upgrade pandas
Try:
sudo apt-get install libatlas-base-dev
It should work now.
Else, try uninstall and reinstall numpy and pandas.
I had the same issue. It was because I had multiple versions of numpy installed. Remove all versions by repeatedly using:
pip uninstall numpy
Then re-install it with the command:
pip install numpy
First, try to import numpy on it's own, like so:
import numpy as np
I got this message:
ImportError: Something is wrong with the numpy installation. While importing
we detected an older version of numpy in
['/home/michael/.local/lib/python3.6/site-packages/numpy']. One method of
fixing this is to repeatedly uninstall numpy until none is found, then
reinstall this version.
So do what it says, keep uninstalling numpy until there is none, and then reinstall.
This worked for me.
I had the same issue while using Microsoft Visual Code with Python 3.7.3 64-bit('base':conda)as my python interpreter. Before running any code type the following three commands:
C:/ProgramData/Anaconda3/Scripts/activate #activate conda Scripts directory
conda activate base #activate conda
& C:/ProgramData/Anaconda3/python.exe #to run python
I have same problem.
I have got two version of numpy 1.16.6 and 1.15.4, fresh installed pandas did not work correctly.
I fixed it by uninstalling all versions of numpy and pandas and install the last versions.
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.16.6:
Successfully uninstalled numpy-1.16.6
Uninstalling pandas-0.24.2:
Successfully uninstalled pandas-0.24.2
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.15.4:
Successfully uninstalled numpy-1.15.4
Cannot uninstall requirement pandas, not installed
$ pip uninstall numpy pandas -y
Cannot uninstall requirement numpy, not installed
$ pip install numpy pandas
I had the same issue with anaconda package, it got updated.
anaconda {4.3.1 -> custom} ## I am not sure if this was the issue
Hit below command to know
conda list --revisions
what i did is just uninstall pandas with conda and re-install it
conda install pandas
Some new libs may also get installed with it.
It worked for me hope will do the same for you.
Uninstall all pip packages that you're having problems with. Manually remove all site-packages files. If you're using MacPorts, sudo port clean .
Then try reinstalling. Sometimes, there are files that should have been removed, but weren't if the installation was abruptly interrupted or something.
There could be an issue with conflicting versions of the package(s), as well as potentially issues with Pathing. Are you sure you've set the correct Path for your binaries? (/opt/local/bin, /anaconda2/bin, etc.)
Another issue could be some PYTHONPATH that's explicitly looking in the wrong place for the file.
I had a same issue recently with Anaconda with Python 3.7.
I solved this problem by downgrading python version to 3.6:
conda install python=3.6
and then by updating all the packages:
conda update --all
pandas is built on top of numpy so you need to have numpy to use the data manipulation feature, so install numpy first.
pip install numpy
This worked in my anaconda environment, but I do not know why conda does not work. For some reason conda uninstall was not sufficient. This only worked with conda remove.
conda remove pandas
conda remove numpy
conda install pip
pip install pandas
*With help from this answer
This raises the following import warning in python 3.6 and 3.7:
ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__
If you with to ignore this warning (and maybe other ImportWarnings), add the following to your script before importing pandas:
import warnings
warnings.filterwarnings('ignore', category=ImportWarning, module='_bootstrap.py')
In my case even though I was using the above options of uninstall and installing using pip the code was still giving me same errors.
Finally, I created a vritual environment and Installed numpy and pandas using pip in my virtual env. Now the code is running.
Steps: for Anaconda3 - Please change according to your installation type:
[if you dont have virtual env package installed]
$ pip install virtualenv
[from command prompt go to the directory by c:\anadonda3\scripts
[write the following command to use virtual env to create a virtual env for you in your desired location]
$virtualenv c:\anaconda3\envs\my_virtual_env
[once created you will have to activate your virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts activate
[now pip install numpy and pandas and other required packages using pip]
[once installations are done exit from the virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts deactivate
now use the python.exe inside your virtual env folder to run the script and it will run even with python 3.7.
I am using Win10 and Conda, and this issue just append to me when upgrading python 3.7.2-h8c8aaf0_0 --> 3.7.2-h8c8aaf0_2.
I solved it by return to the previous version with
conda install python=3.7.2=h8c8aaf0_0
If you're running your program on PyCharm on Windows, there is a known bug, because PyCharm simply doesn't add env-related paths to PATH.
The issue is fixed in the 2019.1 Early Access Preview (EAP) build.
For me installing the EAP fixed the issue.
nothing worked for me ... except when I found this
I suspect that you have a local file called unittest.py that is getting imported instead of the standard module.
I was trying to upgrade my anaconda 2 with anaconda 3. I tried installing Anaconda3-2018.12-Windows-x86 and Anaconda3-2019.03-Windows-x86_64 on my Windows 10 machine and failed with this error. For me, using Anaconda3-4.4.0-Windows-x86_64 for anaconda 3 worked the trick after trying everything listed in answers here.
I fixed this using Anaconda by going to Environments > base(root), searching for numpy in the installed modules and clicking the tickbox alongside it and choosing > Mark for specific version installation > 1.14.0 (as suggested by another user on this thread). Then clicking Apply. Once it downgraded numpy I stopped getting errors when running py files on the command line.
Throughout this saga, I was still able to use https://pypi.org/project/auto-py-to-exe/ even when I was getting the numpy errors on the command line, but it was a hassle to create an exe every time I wanted to test a change. It's all sorted now. I guess there was a problem with numpy 1.16.4.
Anyway, I hope this helps someone who's using Anaconda as well.
The following worked for me.
Deleted the folders for numpy and pandas together with their contents completely from the site-packages folder. Check depending on whether you are using python2 or python3. Check the exact path as per your machine.
N.B handle with care "rm -rf" command. If you are not sure of what you are doing, please do it manually using any file explorer of your choice!!
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/pandas*
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/numpy*
Then i installed clean packages for pandas and numpy as usual with
pip install numpy
pip install pandas
I've got the same error recently. Before applying uninstall or install tools, try to update your Jupyter.
How? Go to 'Environments' and type on the Search Packages box 'pandas'. Afterwards, check the version (if that column shows a blue number with a diagonal arrow, it means that your pandas is out of date). Click on 'pandas' and a option will pop up (choose 'Apply' and wait for a couple of minutes to update the package). And then, make a quick test on any notebook to make sure that your Jupyter is running smoothly.
For those who couldn't solve with the above answers:
Ensure that you are running python3 with
$ python version
If not, install python3.
Then change default python to python3 with
$ alias python=python3
Next, close your jupyter lab/notebook environment and re-launch it with default python being python3.
build_exe_options = {"packages": ["os",'pandas','numpy']}
It works.
you are running python 3.7
create environment for python 3.6
python3.6 filename.py
I am trying to learn pandas and I haven't been able to import it into my code.
I have looked at other answers on this site and none of them have worked.
I just installed anaconda and installed everything through conda.
Here is a sample script that I am trying to run.
import pandas as pd
writer = pd.ExcelWriter('farm_data.xlsx', engine='xlsxwriter')
df.to_excel(writer, sheet_name='Sheet1')
workbook = writer.book
worksheet = writer.sheets['Sheet1']
chart = workbook.add_chart({'type': 'column'})
And the error it kicks back.
Traceback (most recent call last):
File "C:\Users\thiet01\Documents\Python Scripts\new 1.py", line 1, in
import pandas
ImportError: No module named 'pandas'
If you need any more information, please let me know and I can provide it.
Thanks in advance for any help.
below solved my issue:
apt-get install python3-pandas
or
apt-get install python2-pandas
Font: https://ask.fedoraproject.org/en/question/36529/installing-python-pandas/
I had the same problem for a long time. Today I tried a whole day and it finally worked. Below is the steps how I did it. I don't have theory for why the problem exist and how it is solved. I just know the following steps helped me get pandas going.
A. download first and install miniconda using the following code:
bash Miniconda2-latest-MacOSX-x86_64.sh
B. create an env for your project using following code:
conda create --name trypandas numpy pandas jupyter
C. going to your env and try jupyter notebook with pandas using:
source activate trypandas
jupyter notebook
Note: my own experience indicates:
when I missed conda install jupyter, pandas only work in pure python environment, not in ipython nor in jupyter notebook;
after conda install jupyter, pandas works in jupyter notebook now.
the step B above installing jupyter together with numpy and pandas, there should not be a problem.
My trypandas in installed in ~/miniconda2/envs.
Here is the basic documentation on how to instal python packages.
For OS X and Linux users, the following command ought to work:
pip install pandas
Even I had same issue but this solved my problem-
sudo apt-get install python-pandas
To check if pandas is installed or not:
Open up a Python prompt by running the following:
python
At the prompt, type the following:
import pandas
print pandas.\__version__
This will print the installed version of pandas in the system
I wanted to add this as a comment but Im not special enough yet in the eyes of stackoverflow.
Some modules need to be separately installed into your libraries folder of your python directory.Using pip (https://pip.pypa.io/en/stable/) is helpful for this. Otherwise manually add the module to your library folder by installing the module at:
https://pypi.python.org/pypi/pandas/0.18.1/
running the setup through the command line ((pandas location)>setup.py install), and finally adding it to your python directory.
Hope this helps!
What worked for me was to make sure that I run the command sudo apt-get so you run as root to make sure I download python3 like below
sudo apt-get install python3
The reason you need to use sudo it's because environments such as Ubuntu lock the root automatically according to Wikihow
Then I used
sudo apt-get update
sudo apt-get upgrade
And then I used the pip install pandas
That worked for me. I hope that's helpful
For installing pandas you can also use following method in python3.
python3 -m pip install pandas
or
pip3 install pandas
Also if this still fails because of a build error
ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly
or takes a long time to install pandas, then try upgrading pip.
pip3 install --upgrade pip
I am able to import the pandas package within the spyder ide; however, if I attempt to open a new juypter notebook, the import fails.
I use the Anaconda package distribution on MAC OS X.
Here is what I do:
In [1]: import pandas
and this is the response I get:
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
<ipython-input-5-97925edf8fb0> in <module>()

You have more than one Python 2 engines installed. One in your main OS platform, another one inside Anaconda's virtual environment. You need to install Panda on the latter.
Run in your Bash prompt:
which python
Then run the following in Jupyter/IPython and compare the result with the output you got from the Bash script:
from sys import executable
print(executable)
If they differ, you should note the result of the latter (i.e. copy it), and then go to your Bash prompt, and do as follows:
<the 2nd output> -m pip install pandas
so it would be something like this:
/usr/bin/anaconda/python2 -m pip install pandas
And Pandas will be installed for your Anaconda Python.
There is a way to add library paths to your existing environment, using sys.path.append('path to alternative locations'), but this has to be done every time your want to use the alternative environment as the effects are temporary.
You can alternatively install everything in your main environment:
python -m pip install cython scipy panda matplotlib jupyter notebook ipython
Update:
Based on responses to the above section:
Install homebrew like so:
In your Terminal:
xcode-select --install
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
then run:
brew doctor
brew update
brew upgrade
Now go ahead and install Python 2 through Brew:
brew install python
or for Python 3
brew install python3
Or do both. The install other useful stuff!
brew install git conda gfortran clang pkg-config
Then you can go ahead and install your desired libraries either using brew, or using pip, but first you should ensure that pip itself is installed.
easy_install pip
then you can install Python packages like so (NumPy is included in SciPy, and SciPy and Matplotlib depend on Cython and C, Scipy additionally uses fortran for ODE):
python2 -m install cython scipy pandas matplotlib jupyter
you can do that same thing for Python 3.
This clean install should really solve the problem. If it didn't, download Python from Python.org and re-install it. brew sometime refuses to install a package if it finds out that the package already exists. I don't recommend removing Python 2 so that you can install it through brew. That might cause issues with OS X. So the best alternative is to repair existing installations by installing the package downloaded from the website. OS X ensures that the package is installed in the right place. Once this is done, you can then go back to the instructions, but start from brew install python3.
I had the same issue on Mac OS X with Anaconda (Python 2). I tried importing the pandas package in python repl, and got this error:
ValueError: unknown locale: UTF-8
Therefore, I've added the following lines to my ~/.bash_profile:
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
And this has fixed the issue for me.
One thing that you can do it is install the libraries straight in Jupyter, you can try, in the cell:
!pip install pandas
or
!pip3 install pandas
