I updated my custom libtensorflow.so with bazel and I think everything went well, but test TF is failing in Julia so I wonder if the following is correct? pip is updated, Python has latest. Error on test begins with:
> Error: Fatal error on process 2

and my setup is:

Updating TF today showed a move from 0.10.2 to 0.10.4. TensorFlow tests now complete as expected with no error in the testing process, but with 2 tests in error:
```julia
rnn dynamic length
TensorFlow.nn.rnn_cell.LSTMCell
```
