module 'numpy' has no attribute 'losses'

回答:

对于第一个问题，报错 "AttributeError: module 'tensorflow.keras.backend' has no attribute 'get_session'" 的原因是在最新版本的 TensorFlow 中， 'get_session' 方法已经被弃用了。解决这个问题的方法有两种，一种是降级 TensorFlow 版本，另一种是使用 'tf.compat.v1.keras.backend.get_session' 替代 'tensorflow.keras.backend.get_session'。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
