When I Running train1.py using timit data, encountered the following error:

InvalidArgumentError (see above for traceback): No OpKernel was registered to support Op 'NcclAllReduce' with these attrs.  Registered devices: [CPU], Registered kernels:
  <no registered kernels>

[[{{node AllReduceGrads/NcclAllReduce}} = NcclAllReduce[T=DT_FLOAT, num_devices=2, reduction="sum", shared_name="c0", _device="/device:GPU:0"](tower0/gradients/tower0/net1/prenet/dense1/Tensordot/transpose_1_grad/transpose)]]

the folloing the the command line:

python train1.py timit

but how to register the kernel?

[qinyunchuan]

May I uninstall the tensorflow and install tensorflow-gpu?

The args should be ckpt(checkpoint) , (registered gpus) and case (see in pharmacy.py)
Set your dataset path in hparam/hparams.yaml and default.yaml
