tf.one_hot()函数Windows GPU版本报错Error polling for event status: failed to query event: CUDA_ERROR_ILLEGAL_INSTRUCTION;Unexpected Event status: 1

在Windows10的GPU上跑一段普通的TensorFlow代码报错如下

这是因为Windows版本下，GPU版本的TensorFlow里，tf.one_hot()函数有bug，最简单的解决办法是把这个函数放到CPU上(会影响速度，但不会报错)

with tf.device('/cpu:0'):
    b = tf.one_hot(a, 123)

还有一些其他报错也是这个问题，比如这里stackoverflow

E c:\tf_jenkins\home\workspace\release-win\device\gpu\os\windows\tensorflow\stream_executor\cuda\cuda_driver.cc:1177] could not synchronize on CUDA context: CUDA_ERROR_LAUNCH_FAILED :: No stack trace available
