找到在哪儿错了
model.py conv2d那个文件改一下下面这行
把
return tf.nn.conv2d([1, 1, 1, 1], padding='SAME') 改成
return tf.nn.conv2d(x, W, [1, 1, 1, 1], padding='SAME')
没有传入参数当然出错喽
Traceback (most recent call last): File "/home/mnist/convolutional.py", line 11, in <module> y, variables = model.convolutional(x, keep_prob) File "/home/mnist/model.py", line 22, in convolutional h_conv1 = tf.nn.relu(conv2d(x_image, W_conv1) + b_conv1) File "/home/mnist/model.py", line 10, in conv2d return tf.nn.conv2d([1, 1, 1, 1], padding='SAME') TypeError: Value passed to parameter 'input' has DataType int32 not in list of allowed values: float16, bfloat16, float32, float64
同是这个错误 求解答
