针对你遇到的 ImportError: cannot import name '_pywrap_nest' from 'tensorflow.python.util' 问题,我提供以下解决方案: 确认错误原因: 这个错误通常是由于 TensorFlow 的安装问题或环境配置不当引起的。_pywrap_nest 是TensorFlow 内部使用的一个模块,如果无法导入,可能是因为 TensorFlow 的安装不完整或者版本不兼容。

tf.cond支持在tensorflow.python.util.nest中实现的嵌套结构。 true_fn和false_fn都必须返回列表,元组和/或命名元组的相同(可能是嵌套的)值结构。单例列表和元组构成了对此的唯一例外:当由true_fn和/或false_fn返回时,它们被隐式解包为单个值。通过传递strict = True禁用此行为。
