TensorFlow(Mac OS X):无法确定CPU内核数: [英] TensorFlow (Mac OS X): can't determine number of CPU cores:

问题描述

Mac OS X必须有一个简单的设置，才能摆脱以下警告.... bash_profile中的内容?

There must be a simple setting for Mac OS X, to get rid of the following warning...something in .bash_profile?

>>> import tensorflow as tf
>>> sess = 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

推荐答案

要为相关配置选项提供明确的值，您可以执行以下操作:

To provide explicit values for the relevant configuration options, you can do:

NUM_CORES = ...  # Choose how many cores to use.
sess = tf.Session(
    config=tf.ConfigProto(inter_op_parallelism_threads=NUM_CORES,
                   intra_op_parallelism_threads=NUM_CORES))

针对Mac OS X的TensorFlow的初始二进制发行版中存在此问题，但应在以下提交中修复: https://github.com/tensorflow/tensorflow/commit/430a054d6134f00e5188906bc4080fb7c5035ad5

This issue is present in the initial binary release of TensorFlow for Mac OS X, but should be fixed in this commit: https://github.com/tensorflow/tensorflow/commit/430a054d6134f00e5188906bc4080fb7c5035ad5

该修复程序将包含在下一个二进制版本中.同时，您可以按照以下说明尝试从源代码进行构建: http://tensorflow. org/get_started/os_setup.md#installing_from_sources

The fix will be included in the next binary release. In the meantime, you can try building from source, by following the instructions here: http://tensorflow.org/get_started/os_setup.md#installing_from_sources
