'TheanoConfigParser' object has no attribute 'gcc__cxxflags'报错

WARNING (theano.tensor.blas): Using NumPy C-API based implementation for BLAS functions.

 

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The installed Theano(-PyMC) version (1.0.5) does not match the PyMC3 requirements.
It was imported from ['D:\\RJ\\Anoconda\\anoconda33\\lib\\site-packages\\theano']
For PyMC3 to work, a compatible Theano-PyMC backend version must be installed.
See https://github.com/pymc-devs/pymc3/wiki for installation instructions.

当出现这种报错时！也是挺常见的一种错误，此时要记住解决方案：
错因：theno是1.0.5版本的，其与pymc3不匹配，所以我们需要做一件事情。将theno卸载掉，同时安装theno-pymc 1.1.2版本的即可。
输入命令为：
1.pip uninstall theno
2.pip install theno-pymc
问题解决。

 

未报错
