NameError: name 'pyqtgraph' is not defined about magic-class

[hanjinliu]

Hi, @pr4deepr

Thank you for pointing this out, I totally forgot running tests in pure environments...
pyqtgraph is an optional dependency. The NameError is due to an upstream ImportError.

I think that is fixed in the last commit. Sorry.

Thanks for that. I'm getting another error now:

PluginImportError: Error while importing module llsz
================================================================================

[hanjinliu]

Did you installed pyqtgraph to solve the first error?
The second error could be caused by Python<3.9 with pyqtgraph installed, which cannot be tested with current setting...

[hanjinliu]

Anyway, apparently I should move those extension things to another submodule.
Does the current one work?

[pr4deepr]

Hi @hanjinliu
Thanks for this. I had a few dependency issues, so I just removed everything and created a new environment using the latest magic class version. It is working now..
Thanks for your help!

Cheers
Pradeep
