安装TensorFlow时踩的一个小坑
不记得之前安装的是什么版本,这次(2020/3)让pip
自动安装选择的是2.1.0
,但这个版本安装后使用import tensorflow
会报错,如下:
Traceback (most recent call last):
File "[...]\lib\site-packages\tensorflow_core\python\pywrap_tensorflow.py", line 58, in <module>
from tensorflow.python.pywrap_tensorflow_internal import *
File "[...]\lib\site-packages\tensorflow_core\python\pywrap_tensorflow_internal.py", line 28, in <module>
_pywrap_tensorflow_internal = swig_import_helper()
File "[...]\lib\site-packages\tensorflow_core\python\pywrap_tensorflow_internal.py", line 24, in swig_import_helper
_mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
File "[...]\lib\imp.py", line 242, in load_module
return load_dynamic(name, filename, file)
File "[...]\lib\imp.py", line 342, in load_dynamic
return _load(spec)
ImportError: DLL load failed: 找不到指定的模块。
During handling of the above exception, another exception occurred:

报错十分奇怪,提示缺少DLL,但在网上找到的信息只有需要system32
里的msvc140p.dll
可能是问题所在,如果缺少可以安装Microsoft Visual C++ 2015 Redistributable
解决。在检查后发现这个文件已经存在。尝试 https://blog.csdn.net/qq_42580947/article/details/104175457 上的方法后才解决。问题出在版本上,换成2.0.0
正常运行。pip install tensorflow==2.0.0
。另附上国内比较好用的pip

清华大学:https://pypi.tuna.tsinghua.edu.cn/simple/

使用的时候在命令后面加上-i [源]
即可。
