No module named fbx

[yqi19]

Hi, congratulations on your amazing work, when I was trying to install IsaacGymEnvs, I run into the issue that there is no module named fbx, and when I trying to solve it in https://aps.autodesk.com/developer/overview/fbx-sdk it seems that there is no wheel file at all. Then everything gets stuck. Does anyone know why?

Thank you!

I couldn't find the fbx sdk python wheel for python 3.8 either, so I created a new venv with python 3.10 where I could use the FBX Python SDK from the website you mentioned above to import fbx animations.

Yes, I also meet this question, and how did you solve it? @locoxsoco

To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here. The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

@JinQiangWang2021 You can manually edit your /home/jqwang16/isaacgym/python/isaacgym/torch_utils.py and replace np.float by np.float64 at line 135. :+1:
