集群上的Theano安装问题

Question

我正在尝试在运行 "Red Hat Enterprise Linux Client release 5.10 (Tikanga)" 的集群节点上安装 Theano。我没有集群的管理员权限。因此，我在本地用户配置文件中安装了 Theano。以下是我安装的版本详情：

The Python version is : Python 2.7.3

The Numpy version installed on the cluster is: NumPy version 1.6.2

GCC version: GCC 4.6.1

nose version 1.3.4

我按照以下方式安装了Theano

git clone git://github.com/Theano/Theano.git

cd Theano; python2.7 setup.py install --user

The installed Theano version is: 0.6.0

然后我尝试在 python2.7 控制台中运行 theano.test()。在出现以下错误之前，测试顺利运行了几分钟：

请帮我正确安装Theano。我在这个小组中遇到了建议重新安装最新版本的 Theano 的解决方案。但是，我已经从 git 存储库安装了 Theano。我已经尝试过这个可能的解决方案：但我仍然遇到同样的错误。

使用 Theano 标志：blas.ldflags=-lblas -lgfortran

如果您不知道如何使用 Theano 标志，请查看此页面：http://deeplearning.net/software/theano/library/config.html
