【问题描述】：

我在 GPU 服务器上使用 Centos 6.6。我按照here 的说明安装了 mxnet。一切正常，直到我尝试测试安装。我运行以下命令：

python
>> import mxnet

然后我收到错误提示

Check failed: e == fmap_.at(alias) (0x10fc620 vs. 0x103adf0) Entry add_n already registered under different entry

完整的错误信息如下：

我不知道我的安装出了什么问题。服务器有 2 x Nvidia Tesla K80 和 128 GB 内存，它应该足够强大。我希望有人可以给我一些帮助。非常感谢！！！
