Question

有人知道如何解决此问题吗？我正在使用Google Collab尝试运行我的代码，但似乎无法解决此问题。 注意：我在Pycharm中有一个Environment设置，其中没有出现此问题，并且代码运行（由于经过严格的培训，非常缓慢）。 当前在Tensorflow 2.0和Python 3.7上运行

    NameError                                 Traceback (most recent call last)

    669     dqn_agent = DQN(env, cur_state.shape)
    670     dqn_agent.save_model('models/deepq.h5')

如果有人尝试重现此错误，则需要确保collab正在运行tf2而不是tf1

设置协作的先决条件

!pip install box2d-py
!pip install gym[Box_2D]

print(tf.__version__)
# Run next lines if not on tf2
!pip uninstall tensorflow
!pip install tensorflow==2.0.0

尝试在Google Collab中运行Deep Q网络时出现错误“ NameError：名称'base'未定义”
