Question

我正在停止此设置说明：https://machinelearningmastery.com/setup-python-environment-machine-learning-deep-learning-anaconda 但是我在最后遇到了这个问题，我不知道如何解决这个问题：

Answer 1

我有完全相同的错误。在其他论坛上，有人建议MKL 2018中有一个错误。对我来说，问题是通过降级到MKL 2017来解决的。我是通过Miniconda安装的：

conda install mkl=2017

这也意味着降级其他几个依赖包，但我没有遇到任何问题。您还必须确保软件包安装在正确的环境中。让我知道它是否适合你。

Answer 2

我最初将mkl2018降级为mkl2017，但后来遇到了theano和numpy的问题。

对我有用的解决方案就是在错误的底部做它所说的：

设置一个新的环境变量＆＃39; MKL_THREADING_LAYER＆＃39;价值＆＃39; GNU＆＃39;。这个soln（更多细节）来自https://github.com/Theano/Theano/issues/6568

Answer 3

我也遇到了同样的问题：

conda uninstall theano
conda uninstall mkl=2018
conda install mkl=2017
conda install theano

只有那些我需要降级的人。它发生在后来，当我用pip安装其他数据包时，我不小心升级到了mlk = 2018。然后theano正在为我工作仍然工作，不知道如何。
