Error when generating the zarr.zip #18

Closed elevenjiang1 closed 3 months ago

elevenjiang1 commented 6 months ago

Hello, thanks a lot for such great work ! I have run the command 

python run_slam_pipeline.py example_demo_session

However it error when generating the dataset, the errors are shown below:

with av.open(vid_args[0][0]) as container:
IndexError: list index out of range

Any solution?

By the way, I find that the Python code style (both in UMI and Diffusion Policy) you write is so fancy and is hard for me to read (though I also always program by Python), I am curious about what class or book you have learned to write such brilliant code style?

Most likely the path to the example_demo_session folder is wrong. Did you download the example_demo_session in the same folder?

(umi)$ python run_slam_pipeline.py example_demo_session

This command download the files in ~/example_demo_session

Therefore, the following command should be like: (umi)$ python scripts_slam_pipeline/07_generate_replay_buffer.py -o ~/example_demo_session/dataset.zarr.zip ~/example_demo_session

Instead of downloading ~/example_demo_session, the path should be like `pwd`/example_demo_session
