[Python] How to resolve keras.callbacks import errors for TensorBoard?

Attempt 1

from keras.callbacks import TensorBoard

from keras.models import Sequential
from keras import layers
from keras.optimizers import RMSprop
tb_callback = keras.callbacks.TensorBoard(log_dir="/Users/baldur009/Documents/Scripts/log/model_gru", histogram_freq=0, write_graph=True, write_images=True)

model = Sequential()
model.add(layers.GRU(10, input_shape=(None, ts_matrix.shape[-1])))
model.add(layers.Dense(1))
model.compile(optimizer=RMSprop(), loss='mae')
history = model.fit_generator(train_gen,
steps_per_epoch=30,
epochs=30,
validation_data=val_gen,
validation_steps=val_steps, callbacks=[tb_callback])


Error:

NameError
Traceback (most recent call last)
<ipython-input-23-c43bea5e24d5> in <module>()
2 from keras import layers
3 from keras.optimizers import RMSprop
----> 4 tb_callback = keras.callbacks.TensorBoard(log_dir="/Users/baldur009/Documents/Scripts/log/pertussis_gru", histogram_freq=0, write_graph=True, write_images=True)
5
6 model = Sequential()

NameError: name 'keras' is not defined


Attempt 2

Removed

keras.callbacks


So that:

tb_callback = TensorBoard(log_dir="/Users/catherineordun/Documents/Scripts/log/pertussis_gru", histogram_freq=0, write_graph=True, write_images=True)


I received the following error upon running:

---> 22 from tensorflow.contrib import bayesflow
23 from tensorflow.contrib import cloud
24 from tensorflow.contrib import compiler

ImportError: cannot import name bayesflow


As a result, searched and found https://github.com/tensorflow/tensorflow/issues/10811

conda update dask


Continue to receive the same error:

ImportError Traceback (most recent call last)
<ipython-input-48-c43bea5e24d5> in <module>()

So, I read: keras.utils.to_categorical() - name keras not defined, and therefore imported the following to cover as many dependencies as possible:

import keras
import keras.callbacks
from keras.callbacks import TensorBoard


But, continued to face same error.
