I tried to run a python script file on Visual Studio. But the terminal keep pop up saying that I don't have the package installed... I don't know what is going on. I installed Python through homebrew and install all the package through pip3. I even find the path for all the package I have installed, and it's still not working.. I switched between multiple interpreter, and none of them worked, all said my package is not installed.. but it's clearly my package is installed... I even create a new py file to run pandas, and it worked.. Can someone help me with this? This is driving me crazy..
It just because you had chosen the wrong python environment in VSCode.
You said you had created a python file to run pandas and it worked. This means you had installed the package 'pandas' and it worked. But you haven't chosen this environment in your VSCode.
In the terminal:
By command "pip3 --version" to check which pip you are using.
By command "python3" -> "import sys; sys.executable" to check which python you are using.
By command "python3" -> "import sys; sys.path" to check which 'site-package' the interpreter searching for.
From your description, you are using the pip which under '/usr/local', install the packages under '/usr/local/lib/python3.7/site-packages', using python interpreter of '/usr/local/bin/python3'. This is the default python interpreter because of the system environment variables settings. But in VSCode you haven't chosen this environment.
Solution:
Choose an environment or create a virtual environment(recommend). Activate the environment(Ctrl+Shift+`), by the command 'pip3 --version' to check which pip3 you are using, then install the package you want to import.
If you installed python via homebrew try using homebrew to install pandas instead of pip. I've seen things before that they get linked. I would just recommend using pip to uninstall pandas first so there is only package.

Presently I'm using Python on a Windows system. I installed Python 3.10 from Anaconda and also the Pycharm IDE. I have ensured that Python is in the correct path in the environment variable. I have also replicated this problem using two different versions of Python, 3.10 and 3.9.
Very simply, in PyCharm, I open a terminal and type
conda install -c numpy numpy.
Then, I write a new "main.py" script. I have one line: "import numpy". I receive the error:
Traceback (most recent call last):
File "C:\Users\---\PycharmProjects\pythonProject3\main.py", line 17, in <module>
import numpy
ModuleNotFoundError: No module named 'numpy'
What am I doing wrong?
Going on advice from a friend, I created a new PyCharm project sitting not in my user directory but on the C: drive, and got the same error. Finally, when trying to re-install the package using either using either pip or conda, I get this message:
# All requested packages already installed.
You have 2 versions of Python:
Default Python (used everytime you open your command prompt and type python or python3)
Anaconda is installing packages in a virtual environment, using it's own Python (it is located in a different path)
You can see the path of your installed python using python -c "import os, sys; print(os.path.dirname(sys.executable))"
You have 2 Options:
Configure the PyCharm in order to use the anaconda Python. https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#view_list
Open a command prompt in the project's folder (you can do it easily using PyCharm). Type conda env list. This will show you all available anaconda virtual environments. Choose 1 of them and type conda activate <env_name>, where <env_name>=the name of the environment. Then, run your program using python <name_of_your_program>
You can see the paths where the anaconda environments and packages are installed using conda info
There main reason for this is
You are running your main.py in different environment rather than where you installed numpy.
If you trying to run it via cmd use this method
Check which environment you are in right now. refer this and
this. But the most easiest way to do this is use where command
in windows cmd. C:\> where python or C:\> where python3. You will
get the path of activated interpreter.
list conda envs - conda env list
activate conda env - conda activate <env name>
then run this command. pip freeze . and check is there numpy in
the list. If not you have to find and activate the environment where
you have installed numpy.
If you want to run it in pycharm
Refer this on how to change pycharm interpreter.
https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html
Many things can cause this, usually its one of these
You may have to restart your terminal, or IDE if running in there, after installing a package to "refresh" the environmental path
The package is not in the environmental path
I am on Windows 10, running python 3.8.5 and have tried installing PyPDF2 using pip. I've uninstalled and reinstalled several times using these two commands:
"python -m pip install pypdf2"
"py -3 -m pip install pypdf2"
I did this through Visual Studio code being run as my user, as well as the command prompt run as an administrator. The install goes well but I get the error, "Import 'PyPDF2' could not be resolved."
I figure this is due to the file path to the installed package not being included in the PATH system environment variable. So I used "python -m pip show pypdf2" to find the install location:
"c:\users*username*\appdata\local\programs\python\python38\lib\site-packages"
So I added:
"c:\users*username*\appdata\local\programs\python\python38\lib\site-packages\PyPDF2" to my PATH environment variable for both user and system, as well as the PYTHONPATH variable.
After such actions I restarted VS Code, which again is using the python 3.8.5 environment, and still the import could not be resolved.
What am I missing? Any assistance would be greatly appreciated.
I am using python 3.9.6. But when I typed like this in command prompt,
"pip install pypdf2"
it worked for me. Try like this sometimes it'll work.
I'm getting the error in the title when running a .py script. I have pandas installed (version 0.24.2) as you can see in the screenshot. The Python version is 3.7.3. When I run the command import pandas as pd in a Jupyter notebook it works. However, when I have the same command in a .py file ("MyFile.py") and try to run that file using Anaconda command prompt I get this error. Same happens when using the Windows command prompt. Can someone please advise on how to solve this?
The 2nd screenshot above shows that I can't find a folder for pandas in site-packages but anaconda seems to think it's installed.
have you tried python3.7 MyFile.py?
If not, I would try it. Then if it doesn't work I'd create a new environment with python 3.7, and then install pandas and run your code:
conda create -n test_env python=3.7
conda activate test_env
pip install pandas
python MyFile.py
Probably you have installed Python and afterwards Anaconda.
AnaConda has its own python exe and Libs that are automatically installed. They're probably located in (Windows path): C:\ProgramData\AnacondaX\
So, if you go to C:\ProgramData\AnacondaX\Lib\site-packages\ you will see a folder "pandas". It means that Pandas lib is installed for Anaconda exclusively.
On the other hand, you have installed Python in c:\Python27. I'd advise you firstly add to %PATH% environment variable to get access to Python from any folder you're in and after please check the libs you have installed in your Python (not Anaconda) with (pandas is not listed there):
c:>pip freeze
Next step is to install pandas for your Python installation. Just do it:
c:>pip install pandas
Anaconda uses its own python installation, which by default, and as per this documentation, should be under C:\Users\<your-username>\Anaconda3\.
By installing pandas via Anaconda, and then specifically running the script with a different python installation, you're running a script using a library within environment that does not have that library installed.
You can try installing pandas to this separate python installation (I saw your pip install didn't work, you could again specify this python installation and use pip as a module):
'C:\python27\python.exe' -m pip install pandas
Or run the script with the Anaconda python installation by specifying that python installation:
{path_to_anaconda_python} MyFile.py
Where path_to_anaconda_python is path to Anaconda python installation (by default, within C:\Users\<your-username>\Anaconda3\)
I'm trying to install new python modules on my computer and I know how to install through the terminal, but I wish to know if there is a way to install a new module directly through VSCode (like it is possible on PyCharm)?
I already installed through the terminal, it isn't a problem, but I want to install without be obligate to open the terminal when I'm working on VSCode.
You should open the terminal inside the VSCode and install the modules you want.
something like👇
if that's not you meant, please let me know.
First of all I would advise you to select the current Python version you have. It has been explained here:
VSCode: There is no Pip installer available in the selected environment
Next, you should check is the pip installed in your Python main directory or not, by checking how to do on this website:
https://pip.pypa.io/en/stable/installing/
or this thread
How to use pip with Visual Studio Code
by typing
py -m pip
in your terminal, like
C:\Users\m\Desktop\Python> py -m pip
You should have the list of commands and general options which can be used. One of them is install
On the Python library platform, you always have the command to be copied in order to the installation of package you want.
In your terminal, the initial command should look as:
PS C:\Users\m\Desktop\Python> py -m
to which you should append the command prepared on the Python library platform (by copying it and pasting).
C:\Users\m\Desktop\Python> py -m pip install openpyxl
That's it. The package should be installed in your Python folder, what you will see in the terminal.
If everything is alright, you just need to type
import openpyxl #or other package name, which you downloaded
and use it!
Unfortunately! for now, only possible way is terminal.
I try to install Theano by Anaconda. It works, but when I enter the python -i, import theano shows No module named 'theano'. Do I need to switch another interpreter of Python, how? Also, for the packages installed by conda, if I don't double install them, can I find in Python? How is Python related to Python by Anaconda? Thanks!!!
I had have a similar issue, trying to install folium. If you are using the Anaconda:
When you install using conda install -c conda-forge folium, the package will be placed in:
./anaconda3/envs/[name env]/lib/python3.7/site-packages/folium
When you install using pip (with a anaconda env activated), pip install folium, the package will be placed in:
./anaconda3/lib/python3.7/site-packages/folium
Python use first the sites-packages as the target directory of manually built python packages. When you build and install python packages from source (using distutils, probably by executing python setup.py install ), you will find the installed modules in site-packages by default.
In this case you have two places: /anaconda3/lib/python3.7/site-packages/ and /anaconda3/envs/[name env]/lib/python3.7/site-packages/.
First the modules will be available as default in /anaconda3/lib/python3.7/site-packages/. Sometimes (and I really don't know why) the modules inside sites-packages conda env are not available to import automatically without export the PATH.
So, to solve this issue, you have 2 options:
Installing using pip install folium and import folium (don't need install by conda install), or
After conda install , run conda init, close the terminal and open a new one. So, try to import again.
Here are some tips about use a pip in a conda-environment.
You can refer to a specific version of python by using the following at the first line of your .py file
This is for python 2.7
#!/usr/bin/env python2.7
This is for python 3
#!/usr/bin/env python3
As other users already pointed out you need to check if your module is included in your sys path. Use code:
import sys
print(sys.path)
If not you can include this in your sys.path by using the command:
sys.path.append('/path/to/the/folder/of/your/module/file')
or place it in default PYTHONPATH itself.

The problem is that in the code editor you are using, you are running the default interpreter. Based on your code editor, change the python interpreter to the conda interpreter and it will work.
In my case that happened because conda screwed up the environment variables. Instead of using env-specific python and pip, it used the globally installed ones.
Solution:
conda deactivate your-env
conda activate your-env
In my workstation, I was able to solve No module named <module name> error using two different ways.
First method, I solved this temporarily by:
(1) Open a Terminal
(2) $ conda activate <Conda environment name>
(3) $ export PYTHONPATH=/home/<user name>/anaconda3/envs/<Conda environment name>/lib/<Python package version>/site-packages:$PYTHONPATH
It is a temporary solution. Whenever you run your virtual environment, you have to do this.
My runtime environment:
OS: Unbuntu 18.04
Conda version: 4.8.2
Conda-build version: 3.18,11
Python version 3.7.6.final.0
Second method, I removed the
alias python=/usr/bin/python3.6 line in bashrc file.
Somehow this line blocks using Python tools installed in Anaconda Virtual Environment if the Python version in the Virtual Environment is different.
