IndexError: too many indices for array: array is 0-dimensional, but 1 were indexed

Hi, When i execute the demo script i'm getting the following error:

loading 3D models libEGL warning: DRI2: failed to create dri screen libEGL warning: DRI2: failed to create dri screen Unable to initialize EGL Command '['/home/daniel/PoseCNN-PyTorch/tools/../ycb_render/build/test_device', '1']' returned non-zero exit status 1. number of devices found 3 Loaded EGL 1.5 after reload. Traceback (most recent call last): File "./tools/test_images.py", line 183, in cfg.renderer.load_objects(model_mesh_paths, model_texture_paths, model_colors) File "/home/daniel/PoseCNN-PyTorch/tools/../ycb_render/ycb_renderer.py", line 396, in load_objects self.load_object(obj_paths[i], texture_paths[i], scale[i]) File "/home/daniel/PoseCNN-PyTorch/tools/../ycb_render/ycb_renderer.py", line 236, in load_object vertices, faces, materials, texture_paths = self.load_mesh(obj_path, scale) File "/home/daniel/PoseCNN-PyTorch/tools/../ycb_render/ycb_renderer.py", line 344, in load_mesh return self.recursive_load(scene.rootnode, [], [], [], [], offset, scale, [[], [], []]) File "/home/daniel/PoseCNN-PyTorch/tools/../ycb_render/ycb_renderer.py", line 387, in recursive_load self.recursive_load(child, vertices, faces, materials, texture_paths, offset, scale, repeated) File "/home/daniel/PoseCNN-PyTorch/tools/../ycb_render/ycb_renderer.py", line 363, in recursive_load print(np.array(mat.properties['diffuse'])[:3]) IndexError: too many indices for array: array is 0-dimensional, but 1 were indexed

When priting model_mesh_paths, model_texture_paths and model_colors they show the correct path from the models. When i change the lines in ycb_renderer.py

mat_diffuse = np.array(mat.properties['diffuse'])[:3] mat_specular = np.array(mat.properties['specular'])[:3] mat_ambient = np.array(mat.properties['ambient'])[:3] #phong shader

to

mat_diffuse = np.array(mat.properties['diffuse'])#[:3] mat_specular = np.array(mat.properties['specular'])#[:3] mat_ambient = np.array(mat.properties['ambient'])#[:3] #phong shader

it bypass the problem, but gives another error:

I saw this in your message: Unable to initialize EGL It seems something wrong with EGL. You can pull the latest code, go to the ycb renderer fold and run 'python ycb_renderer.py'. Make sure you can run the renderer first.

Same error.

Hey,

I get the same error when running the demo on a NVIDIA Jetson Xavier, python 3.6.9.

Adding some print statements shows that mat.properties['diffuse']=169, so it is an int and not a list, maybe that's a clue?

Well, I should add that there is nothing about being "Unable to initialize EG" in my case.

I had to go back to assimp 4.1.x to get it to work using pyassimp 4.1.3.

I'm on Ubuntu 20.04 which has libassimp-dev 5.0.1 so I built the v4.1.0 from github.com/assimp/assimp.

Thanks. Using:

pip install pyassimp==4.1.3

fixed it for me.

Thank you my friend, I thank you with all my soul. I also hada Ubuntu 20.04 and the trick for me was uninstalling libassimp-dev (If you have already) then building and installing libassimp-dev v4.1.0 with cmake from the source as mentioned above. (building instructions for assimp with cmake is in explained in their github page, then install using "make install")

Thank you,

I have already using assimp 4.1.3 (python 3.8.13), but still failed.

If you're using a conda environment and are also running into this issue: conda install -c conda-forge assimp==4.1.0 followed by reinstalling pyassimp==4.1.3 resolved it for me.

As the above comments, if you are on ubantu 20.04, first uninstall libassimp-dev 5.0.1, then install the v4.1.0. This would solve the problem.
