qtconsole unable to load PyQt5
See original GitHub issueI installed qtconsole using conda.
conda install jupyter qtconsole
Then when I run qtconsole I get:
Icohedron@DESKTOP-80FCK21:~$ jupyter qtconsole
Traceback (most recent call last):
File "/home/Icohedron/.local/bin/jupyter-qtconsole", line 7, in <module>

I then tried to load QtCore from PyQt5 in a Python shell, then QtCore from qtconsole.qt and I got:

I discovered the issue. Bash was running the qtconsole installed through pip in my vanilla (non-conda) python. Despite having
export PATH="/home/Icohedron/miniconda3/bin:$PATH"in my bashrc,jupyter qtconsolestill ran from/home/Icohedron/.local/binand as such did not find PyQt5 installed from conda. I “fixed” this issue by uninstalling qtconsole from my non-conda pip.@2DSharp pyqt is already installed (it automatically installed it with qtconsole as a dependency) and so it doesn’t do anything.
