我正在运行以下代码。我收到如下所述的 XLA 编译器错误。我有 Tensorflow GPU 1.8 版本，但我确实尝试了 CPU 版本，但我收到了错误。但是当我将 Tensorflow (CPU) 降级到 1.3 时，我没有收到任何错误。Tensorflow 已使用带有 Pip 的虚拟环境安装。

请有人可以帮助我。

代码：

import tensorflow as tf
input_tensor = tf.placeholder(dtype=tf.float32, shape=[None, 16, 16, 3])
print(input_tensor.shape)

conv_filter = tf.get_variable('conv_filter', shape=[2, 2, 3, 6], dtype=tf.float32)
conv1 = tf.nn.conv2d(input_tensor, conv_filter, strides=[1, 2, 2, 1], padding='SAME')
print(conv1.shape)

deconv_filter = tf.get_variable('deconv_filter', shape=[2, 2, 6, 3], dtype=tf.float32)

deconv = tf.nn.conv2d_transpose(input_tensor, filter=deconv_filter,
    output_shape=tf.shape(input_tensor),
    strides=[1, 2, 2, 1],
    padding='SAME')
print(deconv.shape)

t = tf.reduce_mean(deconv)
g = tf.train.AdamOptimizer(0.01).minimize(t)

错误日志：

错误即将到来g = tf.train.AdamOptimizer(0.01).minimize(t)

问题的发生是因为过滤器的形状不匹配，以及与之相关的步幅不匹配，以产生具有 V​​ALID 填充的所需输出形状。我应该将反卷积滤波器形状设置为 [1, 1, 3, 3] 并在 [1, 1, 1, 1] 处设置步幅。

所需代码：

deconv_filter = tf.get_variable('deconv_filter', shape=[1, 1, 6, 3], dtype=tf.float32)

deconv = tf.nn.conv2d_transpose(input_tensor, filter=deconv_filter,
    output_shape=tf.shape(input_tensor),
    strides=[1, 1, 1, 1],
    padding='VALID')
