Hey @hatianzhang,

Just wanted to give a friendly ping on this PR. It's been a little over a week since I submitted it, and I understand everyone's busy. I just wanted to make sure it didn't slip through the cracks.

If there's anything I can do to help move this forward or provide additional context, please let me know!

Thanks!

@Dominastorm thanks for your contribution.
We are now in code freeze so I am not going to merge your pr atm. Once our 0.10.0 going out. I will merge this one asap

[logan-markewich]

@Dominastorm apologies, with v0.10.0 the project structure has changed slightly

I can take a stab at porting this PR in a bit, if you don't get to it first :)

[Dominastorm]

@logan-markewich thanks for the offer! I'll port it, no worries :)

[Dominastorm]

@logan-markewich, I have made the changes for porting. I tested it locally and it is working in the python notebook. However, I am unable to understand the test that is failing. If you could let me know what exactly it means, I can get started on fixing it. Thanks!
