Update or install a module from the notebook#
Running pip install from the command line requires to be in the
right folder. And sometimes, several python installations interfere
between each others. Why doing it from the notebook itself:
try:
# pip >= 19.3
from pip._internal.main import main as pip_main
except Exception:
try:
# pip >= 10.0
from pip._internal import main as pip_main
except Exception:
# pip < 10.0
from pip import main as pip_main
pip_main("install -q qgrid".split())

Interesting options#
Avoid installing dependencies#
try:
pip_main("install -q qgrid --no-deps".split())
except Exception as e:
print(e)
Upgrade#
try:
pip_main("install -q qgrid --upgrade --no-deps".split())
except Exception as e:
print(e)
No cache#
By default, pip uses cached version. So, if a module has just been updated, pip might choose to use the previous version. To tell it not to do so:
pip_main("install -q qgrid --upgrade --no-deps --no-cache-dir".split())

For the hackathon…#
pip_main("install pyquickhelper pyensae ensae_projects --upgrade --no-deps --no-cache-dir".split())
