[英]'tensorflow.python.framework.ops.EagerTensor' object has no attribute '_in_graph_mode'
[英]AttributeError: 'Tensor' object has no attribute '_in_graph_mode'
我有一個錯誤:“張量”object 沒有屬性“_in_graph_mode”。 我已經調試過代碼,我認為它在這個GradientTape function 中,但我不知道為什么。 如果有人知道,請幫助我::)
for i in range(50):
with tf.GradientTape() as tape:
inverted_feature = tf.cast(opt_img, dtype)
content_feature = tf.cast(images, dtype)
conv_inverted_outputs = grad_model(inverted_feature)
conv_content_outputs = grad_model(content_feature)
loss = InvertedImage.get_loss(conv_content_outputs, conv_inverted_outputs, content_feature, inverted_feature)
其中grad_model采用特定層的輸入和 output。 此外, opt_img和 * images* 是張量
grads = tape.gradient(loss, [conv_inverted_outputs, conv_content_outputs])
processed_grads = [g for g in grads]
grads_and_vars = zip(processed_grads, [conv_inverted_outputs, conv_content_outputs])
opt.apply_gradients(grads_and_vars)
我得到這個錯誤。

我剛剛遇到了類似的問題(相同的跟蹤)並找到了解決方法,希望它對您的情況也有幫助。
檢查:
conv_inverted_outputs, conv_content_outputs
是 tf.Variable 類型,而不是 tf.Tensor。
如果其中任何一個是 tf.Tensor,您將收到此錯誤。
我看不到足夠的代碼來給出確切的修復,但就我而言,我是通過以下方式生成權重:
weights = tf.random.normal((784, 10))
更改為:
weights = tf.Variable(tf.random.normal((784, 10)))
解決了這個問題。
