tensorflow CUDA_ERROR_UNKNOWN错误

Question

我下载了CUDA Toolkit 8.0 GA2，cuDNN v6.0 for CUDA 8和tensorflow 1.4。我有一个Nvidia 740M图形芯片。我尝试运行此代码来测试tensorflow：

import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))

这就是它的回报：

错误CUDA_ERROR_UNKNOWN是什么意思？我如何解决它？感谢
