導入TensorFlow報錯

C:\....\Anaconda3\envs\py35\lib\site-packages\h5py\__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
from ._conv import register_converters as _register_converters

使用Anaconda安裝的Python3.5環境，導入TensorFlow時出現如下錯誤：

<<<import tensorflow as tf
C:\。..\Anaconda3\envs\py35\lib\site-packages\h5py\__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
  from ._conv import register_converters as _register_converters

解決辦法：安裝Microsoft Visual C++ 2015 Redistributable Update 3 。不再報錯。

啊這個不是導入失敗，應該是字符格式。輸出字符的時候，會在行前有一個b，比如b'Hello TensorFlow!'

在打印行加上.decode()就可以解決了，如下：

print(sess.run(hello).decode())

Hello TensorFlow!
