AttributeError: 'RepeatedCompositeFieldContainer' object has no attribute 'append'
在pycharm中导入tensorflow模块，测试GradientTape函数
相关代码
import tensorflow as tf
with tf.GradientTape() as tape:
x = tf.Variable(tf.constant(3.0))
y = tf.pow(x, 2)
grad = tape.gradient(y, x)
print(grad)
出现如下错误

百度几乎没有类似问题，请教各位大佬，这是怎么回事，应该如何解决呢？
