Hello,

I am trying to train deepspeech on aws instance using tensorflow-gpu
1.13.1 and cuda 9.0 version. I can train the model but when im trying to
do predictions with the model I get the following error:

Warning: reading entire model file into memory. Transform model file
into an mmapped graph to reduce heap usage. slash
Not found: Op type not registered 'AudioSpectrogram' in binary running
on ip-192-168-0-52. Make sure the Op and Kernel are registered in the
binary running in this process. Note that if you are loading a saved
graph which used ops from tf.contrib, accessing (e.g.)
tf.contrib.resampler should be done before importing the graph, as
contrib ops are lazily registered when the module is first accessed. slash
Traceback (most recent call last): slash

raise RuntimeError('CreateModel failed with error code

RuntimeError: CreateModel failed with error code 5

anyone maybe has an idea whats going on?

thanks

Which version of DeepSpeech are you using? This error can occur when
your Tensorflow version is mismatched with your DeepSpeech version.
DeepSpeech 0.4.1 is intended for use with Tensorflow 1.12. The current
master works with Tensorflow 1.13.

That already feels weird, r1.13 is not supporting CUDA 9.0

said, this is a mismatch
at runtime, you need to use binaries >=0.5.0-alpha.6
