TensorFlow报错AttributeError: 'module'无'manip'属性，tf.manip.roll()去向？

Hey there! That error pops up because the tf.manip module was deprecated and removed starting with TensorFlow 2.x. The roll() function you're trying to use has been moved directly into the top-level TensorFlow namespace—no need for the manip submodule anymore.

What to do instead: #

• Replace tf.manip.roll() with tf.roll() directly. The function parameters (like shift, axis) are exactly the same, so you won't have to adjust any of your logic beyond that.

Example code change: #

Before (old TF1.x-style call):

import tensorflow as tf
my_tensor = tf.constant([1, 2, 3, 4])
shifted = tf.manip.roll(my_tensor, shift=1, axis=0)

After (TF2.x-compatible call):

import tensorflow as tf
my_tensor = tf.constant([1, 2, 3, 4])
shifted = tf.roll(my_tensor, shift=1, axis=0)

Quick note: #

If you're still using TensorFlow 1.x, tf.manip.roll() might still work, but this module is deprecated and won't receive updates. It's strongly recommended to switch to tf.roll() even if you're on TF1.x to future-proof your code.
