training dataset

[visanuwan]

I have an issue using the pre-prepared dataset from the command provided in the README.md

$ bonito download --training
$ bonito train --amp /data/training/model-dir

I have successfully downloaded the dna_r9.4.1.hdf5 However, I got an error after running the second command. Could you please guide me? The error message is as follows:

Hey @visanuwan

You can specify the location of the training data with --directory

$ bonito train --amp /data/training/model-dir --directory /data/training/training-data-dir
