nsynth_generate fails with Abseil error (audio generation docs need updating) #47

Followed audio generation instructions and everything went fine until I got to executing nsynth_generate which, with or without arguments, fails with:

andrew@blast:/data/Liles/nsynth/open-nsynth-super/audio/workdir$ nsynth_generate WARNING:tensorflow:From /usr/local/lib/python2.7/dist-packages/magenta/models/nsynth/wavenet/masked.py:116: init (from tensorflow.python.ops.init_ops) is deprecated and will be removed in a future version.

Any suggestions as to a remedy would be much appreciated!

@jesseengel any thoughts on this?

@nsynthsuper ?

Sorry it took so long to respond. I just tested with head of magenta and nsynth_generate seems to work fine.

I think the problem is that directions for setting up the environment in https://github.com/googlecreativelab/open-nsynth-super/tree/master/audio are old now. It's actually pulling from a stale branch of my personal repo.

It should be sufficient to just follow the install istructions at https://github.com/tensorflow/magenta and do pip install magenta-gpu or pip install magenta and then pip install tensorflow-gpu.

@nsynthsuper, want to verify and update the docs?

Many thanks, this did the trick!
