How to modify the dataset path

self.sims[i].newEpisode([scanId], [viewpointId], [heading], [0])

ValueError: MatterSim: Could not open skybox RGB files at: ./data/v1/scans//sT4fr6TAbpF/matterport_skybox_images/6e41a7632c5a4048a17a316d7192b97e_skybox_small.jpg

I think the cause of this error is a bug with './data/v1/scans/', how can I modify this part

@Gaozzzz I have the same problem. Could you solve it?

[Gaozzzz]

@jdiazram sorry, I have not solve it yet

[jdiazram]

@Gaozzzz I solved this by reinitiating all (cloning, docker, everything XD), using the docker, and creating another directory with repo matterport3Dsimulator, installing the minimum for my problem with pip3. And now it's working fine so far.

@jdiazram Thank you very much for your detailed guide. Good luck with your research.

Yes, the cause of this error is the bug with the default data root './data/v1/scans/'.

To fix it, I used the following steps...

1. Open the Matterport3DSimulator project with VScode, then Ctrl + Shift + F to open the search bar and enter the original default path "data/v1/scans". (PS: Do not enter the “/” before “data”);
   
2. Replace your search with your own dataset path, for instance, change all "data/v1/scans" to "/xxx/xxx/v1/scans/";
3. Delete the folder "build";
   rm -rf ./build/
4. Re-execute cmake (These two lines are the same command);
   cmake -D OPENGL_opengl_LIBRARY=/usr/lib/x86_64-linux-gnu/libGL.so -D PYTHON_EXECUTABLE=/home/xxx/.conda/envs/xxx/bin/python3 -DEGL_RENDERING=ON ..
5. Re-execute make;
   make -j8
6. Copy the two compiled .so files into the conda environment's library;
   cp MatterSim.cpython-36m-x86_64-linux-gnu.so /home/xxx/.conda/envs/xxx/lib/python3.6/site-packages
cp libMatterSim.so /home/xxx/.conda/envs/xxx/lib/python3.6/site-packages
7. Rerun the test.
   ./build/tests ~Timing
   

Please note that your paths and mine may differ.
