* Unify the code for training with Keras and TF.Estimator Create a single train.py and trainer.py which uses Keras inside TensorFlow Provide options to either train with Keras or TF.TensorFlow The code to train with TF.estimator doesn't worki See #196 The original PR (#203) worked around a blocking issue with Keras and TF.Estimator by commenting certain layers in the model architecture leading to a model that wouldn't generate meaningful predictions We weren't able to get TF.Estimator working but this PR should make it easier to troubleshoot further We've unified the existing code so that we don't duplicate the code just to train with TF.estimator We've added unitttests that can be used to verify training with TF.estimator works. This test can also be used to reproduce the current errors with TF.estimator. Add a Makefile to build the Docker image Add a NFS PVC to our Kubeflow demo deployment. Create a tfjob-estimator component in our ksonnet component. changes to distributed/train.py as part of merging with notebooks/train.py * Add command line arguments to specify paths rather than hard coding them. * Remove the code at the start of train.py to wait until the input data becomes available. * I think the original intent was to allow the TFJob to be started simultaneously with the preprocessing job and just block until the data is available * That should be unnecessary since we can just run the preprocessing job as a separate job. Fix notebooks/train.py (#186) The code wasn't actually calling Model Fit Add a unittest to verify we can invoke fit and evaluate without throwing exceptions. * Address comments. |
