Question

Whenever I run the cifar10_eval.py, in creates 32 threads as following:

I tensorflow/core/common_runtime/local_device.cc:25] Local device intra op parallelis

Answer 1

To configure this value, you can pass a tf.ConfigProto argument when constructing the tf.Session:

NUM_THREADS = …
sess = tf.Session(config=tf.ConfigProto(
    intra_op_parallelism_threads=NUM_THREADS))
