pip install on Jupyter kerner venv (virtual environment) is not updated - jupyter-notebook

Question

I'm creating the Jupyter kernel within the virtual environment but the pkg in Juypter notebook is still missing after pip install

Answer 1

First create your virtual env using this post and activate it!
Create the kernel using:
ipython kernel install --name=gen-py3
Now the kernel details would be in:
/usr/local/share/jupyter/kernels/gen-py3
note: you can cd to this folder and open the file kernel.json and see the details of your env, for example mine is:
"argv": [
"/usr/local/opt/python/bin/python3.7",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "gen-py3",
"language": "python"
Which means is taken out of the global Python env b/c of this "/usr/local/opt/python/bin/python3.7"
In some cases when you're running in your venv it's constantly taken out of you global env and not your venv. Not try to run in your venv:
virtualenv -p python3 venv
source <env_name>/bin/activate ; in our case venv
pip install ipython
pip install ipykernel
and make sure you run
ipython kernel install --name=venv-test
from your venv ipython.
for example if your virtual env is venv and the location is
~/venv
run:
/Users/nathanielkohn/venv/bin/ipython kernel install --name=venv-test
And your kernel.json file is with the venv:
{
"argv": [
"/Users/<your_user_name>/venv/bin/python",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "venv-test",
"language": "python",
"metadata": {
"debugger": true
}
