cannot import name 'type_spec_registry' from 'tensorflow.python.framework'
问题
我正在进行我的硕士项目，使用MARL，并决定使用RLLib。我为我的项目创建了一个conda环境，并安装了RLLib：
pip install "ray[rllib]" tensorflow
随后，我尝试运行一个实验：
rllib train --algo DQN --env CartPole-v1
但出现了以下错误：“ImportError: 无法从'tensorflow.python.framework'导入名称'type_spec_registry'。”
我正在使用Tensorflow 2.11。
提前感谢！我试图运行一个RLLib库的实验，以测试库是否正确安装。

I am working on my Master's project with MARL, and i decided to use RLLib. I created a conda environment for my project and installed RLLib:
pip install "ray[rllib]" tensorflow
Later on, i tried to run one experiment:
rllib train --algo DQN --env CartPole-v1
But got the following error: "ImportError: cannot import name 'type_spec_registry' from 'tensorflow.python.framework'"
I am using Tensorflow 2.11.
Thanks in advance!

我在安装tf-nightly后，然后回滚到tensorflow v2.11.0后遇到了相同的问题。
我不确定根本原因，但将tensorflow降级到版本2.10.1可以解决这个问题。之后，我可以升级回2.11.0而不会出现导入异常。
# 降级
pip install tensorflow==2.10.1
# 在这一点上tensorflow可以正常工作
# 然后升级到最新版本也可以正常工作
pip install -U tensorflow
英文:
I had the same issue after installing tf-nightly then reverting back to tensorflow v2.11.0.
I'm unsure of root cause, but downgrading tensorflow to version 2.10.1 fixed it on my machine. After this I was able to upgrade back to 2.11.0 without the import exception.
# downgrade
pip install tensorflow==2.10.1
# tensorflow was working at this point
# then upgrading to the latest worked as well
pip install -U tensorflow
