Unable to install pybullet==2.7.9 in Blender's bundled Python

[AkihiroSasabe]

I am able to solve my issue and confirm the operation in the simulator.

Blender's bundled Python cannot install pybullet==2.7.9, but I downloaded a new Python 3.9 separately from blender, and python3.9 -m pip install pybullet==2.7.9 came through. (This may be due to the presence of python3. 9-dev or not? Or eliminating anaconda would have helped.)

In general, Python module installed from outside Blender's bundled Python (in this case, pybullet == 2.7.9) can be executable in Blender's bundled Python by specifying PYTHONPATH with --python-use-system-env option as follows:

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.9/dist-packages:/home/hoge/projects/vgn/src
blender --background --python-use-system-env --python sample.py 

Not that it has anything to do with this issue, run_simgrasp.sh need images in ILSVRC2012 (not ILSVRC2010) so following link in README.md shoud be modified.

GraspNeRF/README.md

Line 35 in 30e2897

Specifically, download [imagenet valset](https://image-net.org/data/ILSVRC/2010/ILSVRC2010_images_val.tar) to `data/assets/imagenet/images/val` which is used as random texture in simulation.

Thanks.
