pip install problem
I cloned the source into my computer several days ago, and use cmd to the file directory and run the instruction "pip install 'socialforce[test,plot]'" and "pip install -e '.[test,plot]'", both return error. First command said "ERROR: Could not find a version that satisfies the requirement socialforce[plot,test] (from versions: none);ERROR: No matching distribution found for socialforce[plot,test]", Second command said "Obtaining file:///F:/GA/socialforce

torch issue "one of the variables needed for gradient computation has been modified by an inplace operation"
HI,
great repo - I want to use it at my classes. It seems the best implementation of SF model in python I have seen. Lightweight and well documented.
Yet I have issues running it, basically torch fails on all the *.generate() calls from your code, like in this example:
import socialforce
import torch
ped_ped = socialforce.potentials.PedPedPotential()
parallel = socialforce.scenarios.ParallelOvertake(ped_ped=ped_ped)
_ = torch.manual_seed(42)
scenarios_1 = parallel.generate(1)
it raises:
RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation: [torch.FloatTensor [2, 2]], which is output 0 of LinalgVectorNormBackward0, is at version 1; expected version 0 instead. Hint: the backtrace further above shows the operation that failed to compute its gradient. The variable in question was changed in there or anywhere later. Good luck!
Installation issue
Maybe that is one of causes, my installation failed on this:
!pip install 'socialforce[dev,plot]'

Why did you modify the constant delta_t?
Dear Mr. Kreiss,
thank you very much for your great implementation.
I'm a master's student, studying pedestrian simulation.
I read Helbing's thesis "Social force model for pedestrian dynamics" and then this repository recently. I am very much interested in your works.
I have just a short question about.......(Helbing's uses 2s for delta_t, and your repository uses 0.4s??).
it would be very helpful if you could answer the above questions for me.
Thank you very much in advance.
Kind regards,
Kenta Kawakami
