我尝试在计算机上启动Tensorflow,但总是遇到“无法识别NUMA节点”错误消息。
我使用的是Conda环境:
- tensorflow -图形处理单元1.12.0
- 库达工具包9.0
- 客户7.1.2
- nvidia-smi说:驱动程序版本418.43,CUDA版本10.1
下面是错误代码:

不幸的是,我不知道该怎么处理错误代码。

我可以用一个新的康达环境来修复它:
这里有一个兼容CUDA/TF组合的表格。在我的例子中,cudatoolkit=9.0和tensorflow-gpu=1.12的组合莫名其妙地导致了std::bad_alloc错误。然而,cudatoolkit=9.0和tensorflow-gpu=1.11.0的组合工作正常。

我也遇到了同样的问题,最后我发现这是因为你使用了Adam来优化模型,一旦你使用了另一个优化器,它应该会工作。
