compute input embeddings error: "no such file or directory"

[nwesthoff]

running $ python 01_compute_input_embeddings.py from ~/open-nsynth-super/audio/workdir to test the pipeline gives me an OSError: [Errno 2] No such file or directory

I split up the subprocess.call to get a more specific line, though I don't think that worked (it breaks on the last line regardless).

Traceback:

Traceback (most recent call last):

all folders exist and are readable, writeable and executable by current user

I think it might have to do something with the wavenet-ckpt folder which contains checkpoint, model.ckpt-200000.data-00000-of-00001, model.ckpt-200000.index and model.ckpt-200000.meta but no model.ckpt-200000

Scratch that. I think it has trouble locating nsynth_save_embeddings, which is in ~/magenta/magenta/models/nsynth/wavenet, not inside the workdir, is this incorrect on my part? or an error in the python script? I'm also not sure what the best way is to fix it.

[nwesthoff]

Reran the entire process of fetching and building magenta, that fixed it. I think that installed nsynth_save_embeddings as a general command.
