AttributeError: module 'numpy' has no attribute 'float' + Confusing FBX Package Error

OS: Ubuntu 20.04
Python: 3.8.0
IsaacGym: Preview 4
Initial error about FBX python library threw me off - this should be removed. Unless the user digs online to find the nvidia employee stating that the FBX library is only used for AMP demo and that this error should be ignored, they will spend a lot of time trying to get the fbx python sdk working, which will fail due to the incorrect version of python (fbx sdk needs python 10).
Actual Error:
Numpy attribute for float is no longer existent for the version of numpy installed via IsaacGym (1.24.0). To fix this, I had to uninstall Numpy 1.24.0 and install the version with the last working usage of the float attribute (1.20.0).
AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. 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
After doing this, training the cartpole demo worked.
Requesting:
Please remove or patch the FBX package error message, and please update the code calling the float attribute that was previously deprecated.

I have same problem with you. And I solve this problem to install numpy <= 1.20.0
