无法获得卷积算法。这可能是因为cuDNN无法初始化，

Question

在Tensorflow /Keras中，从https://github.com/pierluigiferrari/ssd_keras运行代码时，请使用估算器：ssd300_evaluation。我收到此错误。

无法获得卷积算法。这可能是因为cuDNN无法初始化，所以请尝试查看上面是否打印了警告日志消息。

我正在运行的问题：

的Python：3.6.4。

Tensorflow版本：1.12.0。

Keras版本：2.2.4。

CUDA：V10.0。

cuDNN：V7.4.1.5。

NVIDIA GeForce GTX 1080。

我也跑了：

import tensorflow as tf
with tf.device('/gpu:0'):
      a = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[2, 3], name='a')
      b = tf.constant([1.0, 2.0, 3.0, 4.0, 5.0, 6.0], shape=[3, 2], name='b')
      c = tf.matmul(a, b)
with tf.Session() as sess:
print (sess.run(c))

没有错误或问题。

我遇到了此错误，并通过从系统中卸载所有CUDA和cuDNN版本修复了该错误。然后，我为 CUDA 9.0 安装了 CUDA Toolkit9.0 （没有任何补丁）和 cuDNN v7.4.1 。
