Yes, you should reinstall / rebuild DIRT. Tensorflow changes this library from version to version, and DIRT needs to be built with the right one.

The problem with pycharm is likely that an environment variable is set in the terminal, but not in the pycharm run configuration. It's therefore finding a different version of libEGL....

@divyaYK Try adding `--no-deps` to pip command

`libOpenGL.so` is missing. Thus, your nvidia driver/opengl installation is broken. You need to reinstall the driver, or see if `libOpenGL.so` has perhaps been put in a non-standard location (just searching...

`libOpenGL.so` is included in the nvidia driver installation, so something has gone wrong, even if cuda stuff works. It is quite easy to 'lose' the GL libraries as they can...

Yes, it is. If you define your model something like in those in the `samples` folder, it should be differentiable wrt vertex colors, or UVs and texture values. If you...

There is nothing wrong with the code you pasted -- I can't see why the gradients would be zero here. Hence there may be a problem with your `RenderLayer` class...

This means that the install/build did not work correctly. I see you posted lots of comments on other issues, but it is not clear what is current status. Did you...

I don't have any self-contained examples of this currently, but I agree it'd be good to add something. What task are you trying to solve? Different things could be predicted...

Unfortunately I don't have the time to prepare an 'end to end' worked example of training this kind of thing just now. However, wrapping into a keras layer is very...
