Hi @ujjwal96 ,

I am trying to install a ML package iLearnPlus
I made a separate conda environment on Ubuntu 22-04 and followed all the instructions while installing PyQt5 which you have recommended here.
I am still getting an error:

python iLearnPlus.py 
Traceback (most recent call last):
  File "iLearnPlus.py", line 5, in <module>
    from PyQt5.QtWidgets import (QApplication, QMainWindow, QWidget, QDesktopWidget, QLabel, QHBoxLayout, QMessageBox, QAction, QFileDialog)
ImportError: /home/amit/miniconda3/envs/ilearn/lib/python3.8/site-packages/PyQt5/QtWidgets.abi3.so: undefined symbol: _ZdlPvm, version Qt_5

Kindly help. Regards.

Ha! How funny that you got 132 stars for forking a gist of mine that got none. That's the story of my life. ;)

AFAIK I didn't fork anything. I only commented.
