Missing 'burgers.npz' file while training FNO on Burgers` problems

[srinathdama]

When I try to run train_burgers.py, I get the following error as the file burgers.npz is missing.

###############################
Traceback (most recent call last):
  File "/home/neuraloperator/scripts/train_burgers.py", line 74, in <module>
    train_loader, test_loaders, output_encoder = load_burgers_1dtime(data_path=config.data.folder,
  File "/home/neuraloperator/neuralop/datasets/burgers.py", line 52, in load_burgers_1dtime
    with np.load(data_path) as data:
  File "/home/miniconda3/envs/TNO/lib/python3.10/site-packages/numpy/lib/npyio.py", line 427, in load
    fid = stack.enter_context(open(os_fspath(file), "rb"))
FileNotFoundError: [Errno 2] No such file or directory: '/home/ubuntu/data/burgers/burgers.npz'

I could not find burgers.npz in neuralop/datasets/data/. I would appreciate it if someone could help me access it.

Thanks in advance!

Hi @srinathdama, you are correct that we haven't yet released our data file for the 1d Burger's equation. This may change in the future, but for now check out the datasets available on PDEBench
