没有注册 OpKernel 来支持具有这些属性的 Op 'Conv2D'

Question

新手可能有点蠢，但无法将 conv2d 转换为运行

windows10

蟒蛇 4.2.13

python 3.5.2

cudnn 5.1

张量流 0.12

import numpy as np
import tensorflow as tf

graph1 = tf.Graph()
with graph1.as_default():
    f=tf.constant(   np.ones(10).reshape(1,1,-1,1)   )
    g=tf.constant(   np.ones(3).reshape(1,-1,1,1)   )
    conv1=tf.nn.conv2d( f,g, strides=[1,1,1,1] , padding="SAME",name="conv1")

with tf.Session(graph=graph1) as sess:
    sess.run(tf.global_variables_initializer())
    print(sess.run(f))
    print(sess.run(g))
    print(sess.run(conv1))
    sess.close()

结果：

InvalidArgumentError (see above for traceback): No OpKernel was registered to support Op 'Conv2D' with these attrs.  Registered devices: [CPU,GPU], Registered kernels:
  device='CPU'; T in [DT_HALF]
  device='CPU'; T in [DT_FLOAT]
  device='GPU'; T in [DT_HALF]
  device='GPU'; T in [DT_FLOAT]

    [[Node: conv = Conv2D[T=DT_DOUBLE, data_format="NHWC", padding="SAME", strides=[1, 1, 1, 1], use_cudnn_on_gpu=true](Const, Const_1)]]

Answer 1

您应该将两行更改为

f=tf.constant(   np.ones(10).reshape(1,1,-1,1).astype(np.float32)   )
g=tf.constant(   np.ones(3).reshape(1,-1,1,1).astype(np.float32)   )

否则这些节点采用 float64 的默认 numpy 类型，它没有 Conv2D 内核
