nvidia-docker中的TensorFlow：对cuInit的调用失败：CUDA_ERROR_UNKNOWN

Question

我一直致力于使用依赖于TensorFlow的应用程序作为具有nvidia-docker的docker容器。我已将我的应用程序编译在tensorflow/tensorflow:latest-gpu-py3图像之上。我用以下命令运行我的docker容器：

sudo nvidia-docker run -d -p 9090:9090 -v /src/weights:/weights myname/myrepo:mylabel

通过portainer查看日志时，我看到以下内容：

容器看起来似乎正常启动，我的应用程序似乎确实在运行。当我向它发送请求以进行预测时，预测会正确返回 - 但是当我在CPU上进行推断时，我会期望以较慢的速度运行，所以我认为很明显GPU由于某种原因没有被使用。我也尝试在同一个容器中运行nvidia-smi以确保它看到我的GPU，结果就是这样：

我当然不是这方面的专家 - 但似乎GPU从容器内部可见。关于如何使用TensorFlow的任何想法？

Answer 1

我在ubuntu16.04桌面上运行tensorflow。

我使用GPU运行代码的日子很好。 但是今天，我找不到具有以下代码的gpu设备

import tensorflow as tf from tensorflow.python.client import device_lib as _device_lib with tf.Session() as sess: local_device_protos = _device_lib.list_local_devices() print(local_device_protos) [print(x.name) for x in local_device_protos]

当我运行tf.Session()

时，我意识到了以下问题

  

cuda_driver.cc:406]对cuInit的调用失败：CUDA_ERROR_UNKNOWN

我在系统详细信息中检查我的Nvidia驱动程序，并用nvcc -V，nvida-smi检查驱动程序，cuda和cudnn。一切似乎都很好。

然后我去附加驱动程序检查驱动程序详细信息，我发现有很多版本的NVIDIA驱动程序和最新版本。但是，当我第一次安装驱动程序时，只有一个。

因此，我选择一个旧版本，然后应用更改。

然后我运行tf.Session()，问题也在这里。我想我应该重新启动计算机，在重新启动计算机后，这个问题就消失了。

Answer 2

问题可能与GPU创建的JIT缓存文件权限有关。 在Linux上，默认情况下，缓存文件是在〜/ .nv / ComputeCache中创建的。 为JIT cache设置另一个目录可以解决此问题。随便

export CUDA_CACHE_PATH=/tmp/nvidia

在GPU上运行某些东西之前。

我尝试安装nvidia-modrpobe，但仍然是相同的错误。 然后简单的系统重启对我有用
