TensorFlow test failing - my config?


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
│ exception =
│ PyError ($(Expr(:escape, :(ccall(#= /home/colin/.julia/packages/PyCall/0jMpb/src/pyfncall.jl:44 =# @pysym(:PyObject_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) <class ‘TypeError’>
│ TypeError(“can’t pickle traceback objects”,)

and my setup is:

Library Versions

Trying to evaluate ENV[“TF_USE_GPU”] but got error: KeyError(“TF_USE_GPU”)

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:
