我正在为 python3（pip 安装）运行 tensorflow 0.8.0，以及以下文件test.py：

import tensorflow as tf                                                         

a = tf.convert_to_tensor([1], dtype=tf.int32)                               
b = tf.to_float(a)                                                              

with tf.Session():                                                              
    b.eval() 

...运行需要一分钟以上：
