Centos 6.6上mxnet安装报错

Question

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

python
>> import mxnet

然后我得到错误说

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

完整错误信息如下：

我不知道我的安装有什么问题。服务器有 2 x Nvidia Tesla K80 和 128 GB 内存，应该足够强大。我希望有人能给我一些帮助。非常感谢！！！

正如 lynguyen 所回答，这里已进行了修复：github。com/dmlc/mxnet/issues/5255

我已经测试了该解决方案并且它适用于我。我正在使用 gcc-4.8.5，可能是导致此问题的 gcc 版本。谢谢！
