When I used anaconda3's python to run end_to_end_visualize.ipynb, this problem occurred. I copied the system's installed Blender library file to my anaconda3/share/ folder, but it didn't work. I don't know how to solve this problem.

The error message is as follows：

PermissionError Traceback (most recent call last)

I have found the cause of the problem. I linked the wrong Blender file to /usr/local/bin/blender. I solved the problem as follows: After installing the Blender library, execute the command 'which blender', my output is '/usr/bin/blender ', then link this file to '/usr/local/bin/blender' and the error disappears.
