The problem could be that you didn't install all system libs too (I faced this when we were switching to Ubuntu 18.04). Be sure that you installed all things like...

Are you running this on librispeech data (because in config your train data are specified as train-clean-100.lst)? Could you show the running command itself and the full log after you...

Yep, wav format is supported, feel free to use it (for example TIMIT recipe with wav files)

What happens in your log while hanging? seems your batch size is very large, could you try 4 just for test?

Could you run just tests for the flashlight (go to build and run make test)? There are a tests for distributed things, just to be sure they are working for...

Could you check if in flashlight dir all test pass? Distributed test is in flashlight, not in wav2letter.

Probably the reason in mpi itself. @jacobkahn any idea on this?

Ok, seems it is not related to the flashlight and wav2letter itself. Could you try to search this issue at NVIDIA and report them how debug/fix it?

Yep, you are using correct, in both repos, w2l and fl, branch v0.2. Could you check that you linked arrayfire both for fl and w2l cmake? Also can you confirm...

@AlexandderGorodetski, you need to fix `tokensdir` and `tokens`, I guess it is trying to load the paths you used in the training, you can check them in the log printed...
