Anaconda Theano - 安装错误

Question

我正在阅读此设置说明：https://machinelearningmastery.com/setup-python-environment-machine-learning-deep-learning-anaconda 但我最后遇到了这个问题，我不知道如何解决这个问题：

Answer 1

我遇到了完全相同的错误。在其他论坛上，有人建议 MKL 2018 中存在错误。对我来说，问题是通过降级到 MKL 2017 解决的。我通过 Miniconda 安装：

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是按照错误底部所说的去做：

将新的环境变量“MKL_THREADING_LAYER”设置为值“GNU”。这个解决方案（更详细）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

只有我需要降级的那些。后来发生了，我在使用 pip 安装其他数据包时意外升级到了 mlk=2018。但是后来theano为我工作仍然有效，不知道如何。
