Error when preprocessing data

I followed the instructions on how to setup the environment and when I ran the preprocessing script I got many lines with the following two errors.

OpenGL Error 500: GL_INVALID_ENUM: An unacceptable value is specified for an enumerated argument.
In: /usr/local/include/pangolin/gl/gl.hpp, line 205

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

Unfortunately, nothing is generated in the output folder. I have used all the latest versions of the dependencies. I am running the script on a could VM in headless mode. What could be the problem?

I also have met the same problem like: OpenGL Error 500: GL_INVALID_ENUM: An unacceptable value is specified for an enumerated argument. In: /usr/local/include/pangolin/gl/gl.hpp, line 205

However, I could get all processed npz files. But when I tried to train the network, it encountered the error below: Traceback (most recent call last): File "/home/cuili/DeepSDF/train_deep_sdf.py", line 591, in <module> main_function(args.experiment_directory, args.continue_from, int(args.batch_split)) File "/home/cuili/DeepSDF/train_deep_sdf.py", line 511, in main_function chunk_loss.backward() File "/home/cuili/.local/lib/python3.6/site-packages/torch/tensor.py", line 166, in backward torch.autograd.backward(self, gradient, retain_graph, create_graph) File "/home/cuili/.local/lib/python3.6/site-packages/torch/autograd/__init__.py", line 99, in backward allow_unreachable=True) # allow_unreachable flag RuntimeError: leaf variable has been moved into the graph interior

How can I fix it?

I have this same error.

OpenGL Error 500: GL_INVALID_ENUM: An unacceptable value is specified for an enumerated argument.
In: [...]/Pangolin/include/pangolin/gl/gl.hpp, line 205

The npz files are still produced, but the preprocessing runs unacceptably slow, something like 2 minutes per mesh per thread.
