I have installed Anaconda-Package, Flask, Pip & Vscode. I am currently running the development project on localhost using "pipenv shell" command then "flask run" command in vscode.
It works well on http://127.0.0.1:5000/ for simple webapp. But I want to display the prediction charts & tables on a webpage using pandas, numpy etc.
So, When I try to import
import pandas as pd
import numpy as np
It displays this ->
flask.cli.NoAppException
flask.cli.NoAppException: While importing "app", an ImportError was raised:
Traceback (most recent call last):
File "c:\users\mdev\.virtualenvs\flask_md_project-itylmdvv\lib\site-packages\flask\cli.py", line 240, in locate_app
__import__(module_name)
File "D:\flask_md_project\app.py", line 4, in <module>
import numpy as np
ModuleNotFoundError: No module named 'numpy'
above error as image
How do I use pandas,numpy,matplotlib etc from anaconda package along with flask through vscode for my python webapp ? Please help 🙏
According to the information you provided, the modules "pandas" and "numpy" are not installed in the Python environment you are currently using.
When we use the conda environment in VS Code, we use it as a python environment. Therefore, in this environment we need to install the module and then use this module. Usually, the module storage location of conda environment is (for example, base conda environment): "\users\username\anaconda3\lib\site-packages".
We can use the command "pip show pandas" in the VS Code terminal to check the installation location of the module:
For more information about flask in VS Code, you could refer to: Flask Tutorial in Visual Studio Code.
Install numpy on anaconda by running;
conda install numpy

I am trying to use NumPy in Python. I have just installed Anaconda Python 3.7, and that all seemed to go smoothly. However, I cannot import numpy(using the line import numpy). When I do, I get the following error:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy c-extensions failed.
- Try uninstalling and reinstalling numpy.
- If you have already done that, then:
1. Check that you expected to use Python3.7 from "C:\Users\jsmith\anaconda3\python.exe",
and that you have no directories in your PATH or PYTHONPATH that can
interfere with the Python and numpy version "1.18.1" you're trying to use.
2. If (1) looks fine, you can open a new issue at
https://github.com/numpy/numpy/issues. Please include details on:
- how you installed Python
- how you installed numpy
- your operating system
- whether or not you have multiple versions of Python installed
- if you built from source, your compiler versions and ideally a build log
- If you're working with a numpy git repository, try `git clean -xdf`
(removes all files not under version control) and rebuild numpy.
Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.
Original error was:
DLL load failed: The specified module could not be found.
I can see it in the Enviorments tab of Anaconda Navigator, and when I try to use it in Eclipse(Pydev) it shows up under forced builtins. I took a look at my PYTHONPATH, and both my enviorment in Eclipse and my base python directory (jsmith/anaconda3) are in it. I have tried importing other libraries I see under forced builtins,and those work fine, yet numpy seems to be the only one with issues. Calling pip install numpy tells me it is already installed with version 1.18.1. I looked at this stack overflow page, and ran the first command in the answer(conda create -n test numpy python=3.7 --no-default-packages) in anaconda prompt. This worked, and then I realized the test was specific to the question, and tried base instead, and got this error:
CondaValueError: The target prefix is the base prefix. Aborting.
However calling conda activate base did nothing.
As mentioned in the comments by #cel uninstalling and reinstalling numpy using pip uninstall numpy and pip install numpy made it work.
I better way is to
import os
import sys
os.path.dirname(sys.executable)
This will give you the path to your environment. Put the path into the settings for python
Open the Anaconda Prompt:
Then, you have to go to the Conda Environment that you want to use in PowerBI. Am having an environment 'temp', so I activate it first in the 'Anaconda Prompt':
(base) C:\Users\ashish>conda activate temp
Then I go to the directory having the "PowerBI" executable file in the installation folder:
(temp) C:\Users\ashish>cd "C:\Program Files\Microsoft Power BI Desktop\bin"
Then, I launch PowerBI from the Prompt:
(temp) C:\Program Files\Microsoft Power BI Desktop\bin>PBIDesktop.exe
This fixes the NumPy error you are getting. If you want any other package to use with PowerBI, install that package in the respective "Conda Environment" (in my case it is "temp").
Make sure the Python home directory (Anaconda3) has been added to the 'Power BI Desktop' global options in the Python scripting section too.
I have a Colab notebook open and have my files cloned from a github repo. I want to run a python script called models.py. In this file, I am using pandas. When I run this line in Colab:
!python3 models.py
I get the following error:
Traceback (most recent call last):
File "models.py", line 1, in <module>
import pandas as pd
ModuleNotFoundError: No module named 'pandas'
However, if I run in a cell on Google Colab:
!pip3 list
I find that pandas is indeed installed:
pandas 0.25.3
My assumption is that when I run the script, it is not able to see the libraries I have installed but I am unsure how to fix this issue.
If I run:
!which python3
I get:
/usr/local/bin/python3
The python file I am trying to run is under:
/content/my_project/models.py
Should I instead take a different approach to running this file?
Instead of
!python3 models.py
You can use
%run models.py
In a clean Colab runtime, the location of python 3 is different than what you show in your question:
!which python3
# /usr/bin/python3
It looks like you are installing another Python instance in your VM. To ensure you're using Colab's bundled Python 3 executable, try using
!/usr/bin/python3 models.py
If you actually want to use the new python instance you've installed, you'll have to also install whatever packages you need. For example
!/usr/local/bin/python3 -m pip install pandas
I am trying to run a python script from python script.
I tried to run it like this:
os.system("python /opt/mycroft/skills/useridentification-skill/speakerIdentificationProgram/scoring.py")
Then I tried to import the file like this:
import sys
sys.path.append("/opt/mycroft/skills/useridentification-skill/speakerIdentificationProgram")
from scoring import get_id_result
they both returned this error:
File "/opt/mycroft/skills/useridentification-skill/__init__.py", line 9, in <module>
from scoring import get_id_result
File "/opt/mycroft/skills/useridentification-skill/speakerIdentificationProgram/scoring.py", line 2, in <module>
import numpy
ImportError: No module named 'numpy'
just try pip install numpy in your terminal. this will remove error
I think you are using numpy module in scoring.py but you have not installed numpy in your virtual environment.
Use "pip install numpy" after activating your virtualenv.
I assume you followed this to add skills, if so it should install numpy if the skill actually required it
https://mycroft-ai.gitbook.io/docs/mycroft-technologies/mycroft-core/msm
Ref - https://github.com/MycroftAI/documentation/issues/143
Otherwise, you should be using
mycroft-pip install numpy
And you should be source to activate the mycroft venv, and then use the Python command to run your script
Use Panda libraries for data manipulation and file access.

When I try to import the slycot module in spyder (version 2.2), I get the following error:
RuntimeError: module compiled against API version 7 but this version of numpy is 6
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Applications/Spyder.app/Contents/Resources/lib/python2.7/slycot/__init__.py",
line 4, in <module>
from slycot.analysis import ab01nd,ab05md,ab05nd,ab07nd,ab08nd, ab09ad
File "/Applications/Spyder.app/Contents/Resources/lib/python2.7/slycot/analysis.py",
line 21, in <module>
from slycot import _wrapper
ImportError: numpy.core.multiarray failed to import
Now, when I import slycot in the python shell through my terminal, there are no problems at all. I think the reason why there are no problems through the terminal, is that I recently installed numpy 1.7.1. Spyder on the other hand still uses numpy 1.6.2.,hence the error.
I tried to change the numpy version in spyder, but so far that didn't work.
When I change the numpy(6) folder in my spyder lib with the recently installed numpy(7), I get the following error (in spyder):
ImportError: Error importing numpy: you should not try to import numpy from
its source directory; please exit the numpy source tree, and relaunch
your python intepreter from there.
What is the best way to solve this error?
Thanks in advance.
(Spyder dev here) At the moment it's not possible for the user to install anything inside the app. I guess you moved your slycot module from another interpreter to our App (because of the numpy error you mention).
The right way to use different modules not present in the app, is to change the path of your interpreter in:
Tools > Preferences > Console > Advanced settings > Python executable
If you installed slycot using your system Python, you have to select
/usr/bin/python
I have an account in a CentOS server without sudo permission. As a result, I tried to install IPython from source code by python setup.py prefix=<my home directory>.
However, I got the Error:
Traceback (most recent call last):
File "/usr/bin/ipython", line 19, in <module>
from IPython.frontend.terminal.ipapp import launch_new_instance
ImportError: No module named IPython.frontend.terminal.ipapp
I found a question same to mine: IPython import failure and python sys.path in general.
I followed the asker's instruction to add the directory of my IPython to the IPython execution file.
#!/usr/bin/python
"""Terminal-based IPython entry point.
"""
import sys
sys.path.append("./Ipython directory")
from IPython.frontend.terminal.ipapp import launch_new_instance
launch_new_instance()
However, I got the same error as well. So I want to know how can I launch IPython correctly? Thanks.
You probably want to install with the --user flag, which should put it on sys.path automatically.
python setup.py install --user
If you need to use --prefix for some other reason, then make sure that the directory you add to sys.path is the folder containing the IPython package, not the IPython directory. It will probably end with 'site-packages'.
I copied the IPython source folder into ~/bin/. The execution file of IPython can recognize the module in IPython and the IPython shell launches successfully.
