我正在使用Kerassurgeon模块进行修剪。当我在Google colab中使用VGG-16时遇到此错误。它在其他模型上也可以正常工作。有人可以帮我解决这个问题。

尝试Deep learning example with GradientExplainer时,我已经解决了类似的问题。这是由于版本不兼容引起的。
添加以下代码可能会有所帮助:
import tensorflow.compat.v1.keras.backend as K
import tensorflow as tf
tf.compat.v1.disable_eager_execution()
tf版本为2.3.1
kerase版本是2.4.0
夏普版本是0.36

我解决了这个错误。这是由于版本更改所致。请使用Kerassurgeon代替tfkerassurgeon。
使用以下版本
country_iso

我遇到了类似的问题,我已经使用下一行解决了它:
import tensorflow.compat.v1.keras.backend as K
import tensorflow as tf
tf.compat.v1.disable_eager_execution()
答案 3 :(得分:1)
请尝试以下代码:
import tensorflow.compat.v1.keras.backend as K
import tensorflow as tf
tf.compat.v1.disable_eager_execution()
1.compat 允许您编写在 TensorFlow 1.x 和 2 中都可以运行的代码,并且应该 解决基于版本导入的任何错误。
2.eager_execution 是一个接口,一旦调用就允许操作 来自 Python。启用它可以让 Tensorflow 更加直观。
3.但是为什么要禁用eager_execution?
->eager_execution 比 graph_execution 慢。它逐行运行操作
这使得潜在的加速机会毫无用处。
4.运行 tf.executing_eagerly() 以检查 eager_execution 是打开还是关闭。
希望这有助于减少您的错误。
