我尝试更新我的 anaconda，删除用户环境变量中的一些旧路径，重新启动我的系统，再次卸载并安装 keras，但没有任何效果.非常感谢任何帮助.

I tried updating my anaconda, removing some old paths in the user environment variables, restarting my system, uninstall and install keras again, but nothing worked. Any help is extremely appreciated.

推荐答案

我遇到了同样的问题.它似乎与Theano有关.对我来说，我解决了

I had same problems. It seems related to Theano. For me, I solved it by

> conda uninstall tensorflow theano
> conda install -c anaconda tensorflow

如果我安装例如pymc3 拉入 theano，我又遇到了同样的问题.

If I install e.g. pymc3 which pulls in theano, I have the same problems again.
