Moving import of visualization library inside of function

[senickel]

This will prevent the installation of additional packages on linux when not using visualizations (e.g., when working running code in a container).

@senickel thanks for the request and good spot... I've gotten a bit lazy recently and appreciate your feedback!

Suggest you review the PEP 8 guidelines on imports here. I think a nicer way to handle this would be to import the PLOTLY variable from visual and then:

if PLOTLY:
    return figure(self, type, **kwargs)
else:
    return None

Or perhaps print("Please pip install plotly to enable figures") or something similar to prompt this dependency be installed?

[jonnymaserati]

Think you need to update your .gitignore file - these files should be in the repo.

[jonnymaserati]

Same comment as previous - suggest from .visual import PLOTLY and to conditionally return the fig.

[jonnymaserati]

Same comment here, make it conditional on visual.PLOTLY.

[jonnymaserati]

Yes! Good spot @nicolaphee. I've been flip flopping between vedo and vtk and was too lazy to add this. This needs cascading through the module though.

[jonnymaserati]

How to nicely handle when VEDO is False?

[jonnymaserati]

How to manage if not VTK?

[jonnymaserati]

Good stuff, but it would be nice to inform the user that for this functionality pip install vtk, either when the library is initiated or when the class is called?

[jonnymaserati]

Don't forget to bump the __version__ number in .version.

Hi @jonnymaserati!
I finally have some time to review your comments. Thanks a lot for responding and for the great library as well!

Somehow your comments are not referencing any particular code lines on my side. Hence, where I wasn't sure what the comment was about I added 👀

I also changed visual.py to raise an ImportError if the vtk or vedo are not installed but are needed to execute something.

Let me know what you think!
