I need help understanding venv and project management on a Windows 7 system.
I have installed Python 3.7.4. Running the command ‘pip list’ results in the following:
Package Version pip 19.0.3 setuptools 40.8.0
Under the path C:ProjectsNeuralNetworks I have the following files/folders:
project_env #virtual environment created with venv main.py
When activating my virtual environment ‘project_envScriptsactivate.bat’ the command ‘pip list’ results in:
Package Version numpy 1.16.4 pip 19.0.3 setuptools 40.8.0
When I go to run main.py I get the error “NameError: name ‘numpy’ is not defined”.
#main.py import numpy as np print(numpy.version.version) input('Press enter to continue...')
I expect to see the version of numpy but instead I get the error that numpy is not found which tells me I don’t really understand how these directories work.
Solution: I added runserver.bat to my project directory with following.
CALL C:ProjectsNeuralNetworksproject_envScriptsactivate.bat python C:ProjectsNeuralNetworksmain.py runserver
I run the runserver.bat and everything works perfectly.
You need to create a .bat file where you added some code inside to activate the environment first and then run your python file.
something like :
@echo off cmd /k "cd /d ..envScripts & activate & cd /d ..foldername & python main.py
