Error with keras.callbacks.Tensorboard for visualizing Emebeddings

[boardw...@gmail.com]

Hello,

I am using:

keras 2.3.0

tensorflow 1.14.1

python 3.7.4

Ubuntu 16.04.6

and try to visualize embeddings within tensorboard:

hereafter my code:

# logs tensorboard
    tensorboard_callback=keras.callbacks.TensorBoard(log_dir=logs_path+"logs/lstm_{}".format(time()),histogram_freq = 1,embeddings_freq = 1,embeddings_layer_names="my_embeddings",embeddings_data=train,embeddings_metadata={'my_embeddings':my_path+labelfile})

If I do not use the embeddings parameter (see 4 parameters belows), everything works fine.

But with embedding parameters, I get the following error:

Traceback (most recent call last):
  File "/home/ypsa6500/anaconda3/envs/tensorflow_gpuenv/lib/python3.7/site-packages/tensorflow/python/client/session.py", line 1356, in _do_call
    return fn(*args)

    run_metadata)
tensorflow.python.framework.errors_impl.FailedPreconditionError: Error while reading resource variable Variable from Container: localhost. This could mean that the variable was uninitialized. Not found: Resource localhost/Variable/N10tensorflow3VarE does not exist.
     [[{{node my_embeddings_embedding/Initializer/ReadVariableOp}}]]

Remark:

- with other version of keras and tensorflow (older version) where Tendorboard do not require "embedding_data" parameter, everything works fine.

- the keras online documentation, uses : keras.callbacks.tensorboard_v1.Tensorboard which I have tried as well, I get error as well (not the same)

Endly, can you say me how I can use keras callback to visualize embedding in tensorboard (with the version described above) ?

Any idea @fchollet ?
