Hello every one,

I have trained an agent and I saved the model. Now, I move the saved model on another system, I get this error:

File “/usr/local/lib/python3.8/dist-packages/ray/tune/trainable/trainable.py”, line 783, in restore  
self.load\_checkpoint(to\_load)  
File “/usr/local/lib/python3.8/dist-packages/ray/rllib/algorithms/algorithm.py”, line 2004, in load\_checkpoint  
checkpoint\_data = Algorithm.\_checkpoint\_info\_to\_algorithm\_state(  
File “/usr/local/lib/python3.8/dist-packages/ray/rllib/algorithms/algorithm.py”, line 2562, in \_checkpoint\_info\_to\_algorithm\_state  
worker\_state[“policy\_states”][pid] = pickle.load(f)  
ModuleNotFoundError: No module named ‘tensorflow.python.trackable’

Could you help me how to solve this problem?

Thanks,

---

You might want to reinstall tensorflow.  
Make sure that Tensorflow is up to date with Rllib’s requirements.  
Please also make sure that the checkpoint is from the same Ray version.
