Theano导入错误

Question

我正在尝试在CPU机器上安装Theano(运行intel HD图形,没有NVIDIA).我在python中测试时遇到以下导入错误.

WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to exe
cute optimized C-implementations (for both CPU and GPU) and will default to Pyth
on implementations. Performance will be severely degraded. To remove this warnin
g, set Theano flags cxx to an empty string.
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\anaconda\pkgs\theano\theano\__init__.py", line 74, in <module>
    from theano.printing import pprint, pp
  File "c:\anaconda\pkgs\theano\theano\printing.py", line 19, in <module>
    if pd.find_graphviz():
  File "C:\Anaconda\lib\site-packages\pydot.py", line 409, in find_graphviz
    "SOFTWARE\ATT\Graphviz", 0, win32con.KEY_QUERY_VALUE )
pywintypes.error: (2, 'RegOpenKeyEx', 'The system cannot find the file specified
.')

我安装了g ++.

谢谢.

如文档中所述,确保在使用Anaconda时已完成此操作.

conda install mingw libpython
