TensorBoard Keras Callback fails, if input type is tf.string

See original GitHub issue

TensorBoard Version: 1.9.0 TensorFlow Version: 1.9.0 OS: macOS 10.13.6 Python Version: 2.7.10 / 3.6.4

Hi,

TensorBoard exists with the following error, if one of the input layers has the input dtype=tf.string:

  File "train.py", line 236, in train
    validation_data=(X_val, y_val), callbacks=[early_stop, checkpoints, tensor_board])
  File "~/venv/lib/python3.6/site-packages/keras/engine/training.py", line 1705, in fit
    validation_steps=validation_steps)
  File "~/venv/lib/python3.6/site-packages/keras/engine/training.py", line 1155, in _fit_loop
    callbacks.set_model(callback_model)
  File "~/venv/lib/python3.6/site-packages/keras/callbacks.py", line 52, in set_model
    callback.set_model(model)
  File "~/venv/lib/python3.6/site-packages/keras/callbacks.py", line 782, in set_model
    layer.output)
  File "~/venv/lib/python3.6/site-packages/tensorflow/python/summary/summary.py", line 203, in histogram
    tag=tag, values=values, name=scope)
  File "~/venv/lib/python3.6/site-packages/tensorflow/python/ops/gen_logging_ops.py", line 283, in histogram_summary
    "HistogramSummary", tag=tag, values=values, name=name)
  File "~/venv/lib/python3.6/site-packages/tensorflow/python/framework/op_def_library.py", line 609, in _apply_op_helper
    param_name=input_name)
  File "~/venv/lib/python3.6/site-packages/tensorflow/python/framework/op_def_library.py", line 60, in _SatisfiesTypeConstraint
    ", ".join(dtypes.as_dtype(x).name for x in allowed_list)))
TypeError: Value passed to parameter 'values' has DataType string not in list of allowed values: float32, float64, int32, uint8, int16, int8, int64, bfloat16, uint16, float16, uint32, uint64

If I change the input of the layer to int32 TensorBoard works fine (nothing is added though), however as expected the training fails. The layer is just a simple Input layer: Input(shape=(None,), dtype=tf.string).

Best, Timon

Could you try with the latest 2.0 nightly? I am not seeing this issue there
