How to run *.pt file trained using OpenNMT-py in a different Python script?

Question

I have trained Hindi-English parallel language corpora using OpenNMT-py, after running to some epoch I got checkpoints as 10k.pt, 5k.pt, etc.

Now I want to use that .pt file in a different Python script.

How to do it?

Following are my configurations:

• OpenNMT-py = 3.4.3
• Python = 3.10.13
• torch = 2.1.2+cpu
