Your session crashed for an unknown reason
when I run the following cell in Google Colab:
from keras import backend as K
if 'tensorflow' == K.backend():
import tensorflow as tf
from keras.backend.tensorflow_backend import set_session
config = tf.ConfigProto()
config.gpu_options.allow_growth = True
config.gpu_options.visible_device_list = "0"
set_session(tf.Session(config=config))
I receive this message since I have uploaded two data sets to google drive.
Does anyone know this message and can give me some advice? Many thanks for every hint.
Update: I always receive the message
Update I have removed the data sets from Google Drive, but the session is still crashing.

Google Colab is crashing because you are trying to Run Code related to GPU with Runtime as CPU.
The execution is successful if you change the Runtime as GPU. Steps for the same are mentioned below:
Runtime -> Change Runtime -> GPU (Select from dropdown).
Please find the Working code in Github Gist.

Just a side note: sometimes you may want to reinstall an litle older version of the related module (see from the error log). It works for me in a case.
