Answer 1

Had same issue in OSX when updating tensoflow to 1.13 using conda.

• Solution 1: /gcamargo worked but 3x slower per training epoch.
• Solution 2: /sjcoding worked and removed serious warining but also 3x slower in training.
• Solution 3: that restored performance was: Install pip in new conda env and use pip to install tensorflow. Using conda-forge also worked but version of tf is old.

Apparently the new Intel-MKL optimizations in Anaconda are broken for OSX tensorflow.
