ModuleNotFoundError: No module named 'MatterSim'

Traceback:

ModuleNotFoundError: No module named 'MatterSim'

I'm using Google Cloud Platform, running an Ubuntu 18.04 VM.

After mounting the docker container, I have run the following commands from inside the container:

• mkdir build && cd build
• cmake -DEGL_RENDERING=ON ..
• make
• cd ..

The next statement gives the above error:

• python3 scripts/downsize_skybox.py

Alternatively, I've also tried the following cmake command, but got the same error:

• cmake -DEGL_RENDERING=ON -DPYTHON_EXECUTABLE:FILEPATH=/usr/bin/python3.6 ..

How do I preprocess the skybox images? I understand that without this step, I cannot use the simulator.
Can using the Simulator API be an alternative workaround to this error?

Assuming the make command runs without error, it looks like python is not looking in the correct place for the MatterSim package.

This looks like a python issue. The python import system is complex and the settings vary by machine so I can't provide support for debugging that.

I solved the problem by adding the build folder to PATH in bash, or you can do it within python:

import sys
sys.path.append('Matterport3DSimulator/build')

then the import will run successfully.
