GPU requirements

New project for OpenCap, which is a new software package to estimate 3D human movement dynamics from smartphone videos. OpenCap strongly relies on OpenSim.

GPU requirements

Post by Herman van Werkhoven » Mon Apr 10, 2023 12:11 pm

Hi there,

I had three questions related to the OpenCap GPU requirements:
* To run the pipeline locally it states the minimum requirements of a CUDA enabled GPU. Does this imply that it has to be a NVIDIA GPU I assume?
* Is it possible to run this pipeline through Google Colab?
* Do you need the GPU to run the kinetics analysis (example_kinetics.py) locally?

I would appreciate your feedback.

Regards,
Herman

Hi Herman,

- You should be able to run our pipeline locally with other types of GPU, but we have never tested. You might need to deviate from our install instructions.
- That's a good question. Again, we have never tested. But I see some existing notebooks for OpenPose (https://colab.research.google.com/githu ... Pose.ipynb) so it might be possible.
- No, the kinetics part only requires CPU.

Best,
Antoine
