如何使我的Numpy / Scipy使用ATLAS而不是OpenBLAS（在虚拟环境中）？

Question

我的numpy和scipy使用OpenBLAS，这导致了scikit-learn的多处理问题。 scikit-learn高级安装instructions表示应该使用ATLAS而不是OpenBLAS。我不知道如何使用ATLAS代替OpenBLAS进行numpy / scipy。我尝试了如下的说明，但仍然numpy配置说它使用OpenBLAS。我也试过this，但是numpy，scipy仍然使用OpenBLAS并且代码冻结了。更新替代命令清楚地显示选定的地图集，所以我不明白为什么numpy和scipy配置仍然显示正在使用OpenBLAS。我正在使用Ubuntu＆＃34; 16.04.3 LTS（Xenial Xerus）＆＃34;环境。
