How to active Virtual environment form python script(.py) without shell script (.sh)? [duplicate]

Question

I have a requirement to run my code in python virtual environment, for that I am trying to active the virtual environment through the python script only.

But getting error as: /bin/sh: 1: source: not found

cmd = "source ./nnvm_ndk_tools_env/bin/activate"
process = subprocess.Popen(cmd, stdout=PIPE, shell=True)
Above commands I have added in below script and run the script
python test.py

Output:
source ./nnvm_ndk_tools_env/bin/activate
/bin/sh: 1: source: not found

Can anyone please reply? I have to active the virtual env through python script only.

Possible duplicate of "source" command in shell script not working, Difference between sh and bash, etc. More generally, command source does not work site:stackoverflow.com — jww

Hi Firstly you have to install virtualenv then create a virtual environment activate that Virtual Environment and then install all python packages you want in that virtual env. Like below

pip install virtualenv
virtualenv myenv

then a virtual env is created in your directory go to that directory

cd myenv
cd Scripts

then simply run a file 'activate'

activate

you can install your packages here Let me know if you still find problem
