Hi, were you able to fix this problem?

[SchweitzerGAO]

I also have this problem, so kind of you if you can provide a possible solution!

[jufi2112]

Assuming that for you, the error also occurs if you want to visualize the created mesh on top of the original image (--visualize="True" option): I ended up copying some of the original visualization code and wrote my own routine that does this visualization after the fitting process is done, see https://github.com/jufi2112/smplify-x/blob/dc8d58c80430c629d00fd151f450f2d61fb4b132/vis_on_image.py

So I run SMPLify-X with visualization disabled, which, for me, prevents the error. If you are somehow dependent on having the visualization done during the fitting, I'm afraid I have no solution for you at this time. I will, however, come back here if I randomly stumble upon a solution.

As an interesting side note to this problem: If I only fit one image, I get no problems. The error only occurs after I try to fit multiple images. Therefore, I assume that something with the way the Viewer is handled is not correct. However, I use a system configuration different from the one the authors tested their code on, so this might have something to do with the problem.

Thanks @jufi2112 the problem was solved and it works well now!

[y-71]

@SchweitzerGAO it still breaks for me

Is there any PR merged for this sake?

[SchweitzerGAO]

@y-71 Hi there, this has been long and I forgot about how I dealt with this concretely, sorry about that... Maybe I just disabled the visualization part and this worked.

jufi2112 your code does not work for me!

[jufi2112]

You also need to add the following line: https://github.com/jufi2112/smplify-x/blob/8e594c1e521fbaed1a62e88ad945b36827130022/smplifyx/fit_single_frame.py#L469

This is because the camera center is not part of the original result dict

@jufi2112 mmhhhhhmmmm, this means that I'll need to re-launch the inference again? :'(

Thank you for the fast feedback! I'll try this out!

I had this problem on Windows whenever the pyrender.Viewer was called a second time, my solution was setting run_in_thread=False in 54th line https://github.com/vchoutas/smplify-x/blob/master/smplifyx/mesh_viewer.py#:~:text=%3DFalse%2C-,run_in_thread%3DTrue%2C,-registered_keys%3Dregistered_keys
