CP decomposition works only once

[frupniew]

I have a problem with running CP decomposition. It works only once, then I have to restart runtime on google colaboratory. I wrote details here: https://stackoverflow.com/questions/56304037/do-i-have-to-restart-colaboratory-runtime-every-time I also tried to use similar method as in answer to HOOI for i in range(2): g1 = tf.Graph() ... but it didn't help.
