Hello,

Thanks for the repository and nice documentation.

When running the end_to_end example with BachelierNet, I ran into the following error:

RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.FloatTensor [20, 40]], which is output 0 of SubBackward0

(using torch == 2.1.2 on cpu)

I fixed it by changing the inplace operation in CovarianceMatrix.compute_covariance (misc.py line 136, check the PR change).

@louisoutin thank you for the PR and sorry it took me so long to have a look:)

I will play around with it a little bit (e.g. fixing the CI) and hopefully merge soon:)
