How much RAM required for training?

[Anthony Proschka]

I am able to set up environment on Windows. Now that I run training I run into this issue:

Traceback (most recent call last):
File "F:\4D-Facial-Avatars\nerface_code\nerf-pytorch\train_transformed_rays.py", line 602, in <module>

Dear sir,
I am currently exploring the work also on Windows.
I ran into the same issue raised by you above. I would like to humbly ask if you could provide any solutions?

Thank you so much in advance
