系统:win10
已安装anaconda
安装tensorflow时,出现distributed 1.21.8 requires msgpack, which is not installed.错误;
此时使用安装
msgpack无法解决问题
解决方案:使用管理员权限打开dos
再使用pip命令安装
msgpack
回到普通权限的dos,使用pip安装tensorflow
即可安装成功!
在python shell 中运行测试代码:
>>>
import
tensorflow
as
tf
>>> hello = tf . constant ( 'Hello, TensorFlow!' )
>>> sess = tf . Session ()
>>> print ( sess . run ( hello ))
>>> hello = tf . constant ( 'Hello, TensorFlow!' )
>>> sess = tf . Session ()
>>> print ( sess . run ( hello ))
会出现警告信息: 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
from ._conv import register_converters as _register_converters
退回到dos中
输入命令pip install h5py==2.8.0rc1
上述warning可以解决
如果出现警告
I T:\src\github\tensorflow\tensorflow\core\platform\cpu_feature_guard.cc:140] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2
说明CPU不支持
AVX2;
在代码前加:
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
警告可消除。
但CPU处理速度依然会变慢;
使用GPU可避免这个问题。
