Domino Valdano updated MADLIB-1426:
-----------------------------------
Description:
Whenever I try to run {{madlib_keras_fit_multiple_model()}} on a system without
GPU's, it always fails in evaluate complaining that device {{gpu0}} is not
available. This happens regardless of whether {{use_gpus=False}} or
use_gpus=True.
My platform is OSX 10.14.1 with latest version of madlib (1.17.0) and gpdb5. I
think I've also seen this happen on CentOS in gpdb6, so I believe this is a bug
that affects all platforms, but not entirely sure of that. Possibly specific to
OSX or gpdb5.
The problem happens in {{internal_keras_eval_transition()}} in
{{madlib_keras.py_in}}.
With {{use_gpus=False}}, it runs:
{{with K.tf.device(device_name):}}
{{ res = segment_model.evaluate(x_val, y_val)}}
I added a {{plpy.info}} statement to print {{device_name}} at the beginning of
this function. I also printed the value of {{use_gpus}} on master before
training begins. While {{use_gpus}} is set to false, the {{device_name}} on the
segments is set to {{/gpu:0}}. This is the bug (it should be set to {{/cpu:0}}).
This is the error message that happens:
