resolution = 0.4, n_iterations = 1000)

a problem occurs :
Error in py_run_file_impl(file, local, convert) :
ModuleNotFoundError: No module named 'leidenalg'

Detailed traceback:
File "", line 10, in
File "D:\Win10 System\Documents\R\win-library\4.1\reticulate\python\rpytools\loader.py", line 44, in _import_hook
level=level

So,i checked this :

And using conda, i found this: leidenalg is there!!!

And then i tried this : Although leidenalg , pandas AND pillow is in my evrironment,but only pandas could be uesed.
