Anaconda Theano - 安裝錯誤

Question

我正在暫停這個設置說明： https ： //machinelearningmastery.com/setup-python-environment-machine-learning-deep-learning-anaconda但是我在最后遇到了這個問題，我不知道如何解決這個問題：

(base) C:\Users\andrz>python deep_versions.py

Answer 1

我有完全相同的錯誤。 在其他論壇上有人建議MKL 2018中有一個錯誤。對我來說，問題是通過降級到MKL 2017來解決的。我通過Miniconda安裝：

conda install mkl=2017

這也意味着降級其他幾個依賴包，但我沒有遇到任何問題。 您還必須確保軟件包安裝在正確的環境中。 請讓我知道這對你有沒有用。

Answer 2

我最初將mkl2018降級為mkl2017，但后來遇到了theano和numpy的問題。

對我有用的解決方案是在錯誤的底部做它所說的：

將新的環境變量“MKL_THREADING_LAYER”設置為值“GNU”。 這個解決方案（更詳細）來自https://github.com/Theano/Theano/issues/6568

Answer 3

我也有同樣的問題：

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

只有那些我需要降級的人。 它發生在后來，當我用pip安裝其他數據包時，我不小心升級到了mlk = 2018。 然后theano正在為我工​​作仍然工作，不知道如何。
