cosmoflow: yaml file for the small example

[laszewsk]

Steve, please can you send me or check in a yaml file for the small example. For some reason when I try to modify parameters to use the small dataset its not properly working

Thanks

Hi Gregor,

The easiest thing if you just want to test is to just use the regular cosmo.yaml config and override the settings for number of samples, e.g. command line args --n-train 64 --n-valid 64 or in the yaml:

data:
    ...
    n_train: 64
    n_valid: 64

I don't have a "mini" dataset that's compatible with MLPerf HPC v1.0 and v2.0. There is only the single big tarball: https://github.com/mlcommons/hpc/tree/main/cosmoflow#mlperf-hpc-v10-preliminary-dataset

Alternatively, for a small test, you could try the dummy dataset config: https://github.com/mlcommons/hpc/blob/main/cosmoflow/configs/cosmo_dummy.yaml
Unfortunately I haven't tested it in a while, but if you have problems I could try to fix them.

Steve
