Warning while creating Session on Mac OS X: can't determine number of CPU cores#27

While creating a Session, I get this warning (using pre-built whl on OSX). Any ideas?

s = tf.Session()
can't determine number of CPU cores: assuming 4
I tensorflow/core/common_runtime/local_device.cc:25] Local device intra op parallelism threads: 4
can't determine number of CPU cores: assuming 4

    Hi delip, we fixed this in 430a054 -- when we mint our next version of the pip binaries, this should be fixed. Thanks for your report!
