checkpoint file extension is .cptk, not .ckpt

[yosider]

The extension of my checkpoint files are .cptk, not .ckpt.
Is this a typo at this line?

ml-agents/ml-agents/mlagents/trainers/tf_policy.py

Line 325 in 66c9f76

last_checkpoint = self.model_path + "/model-" + str(steps) + ".cptk"

Hi @yosider -- I think you're right that the checkpoints should be .ckpt. I'll bring this issue up with the team.

Thanks for the report @yosider. I've made the fix in #3470. Going to close this issue, but please let us know if you run into any more problems.
