The correct argument is --init-model model.ckpt.

The correct argument is --init-model model.ckpt.

Thank you for your reply!

I use this directive: dp train --init-model model.ckpt.index init-model.json, and still report: TypeError: expected str, bytes or os.PathLike object, not NoneType

The checkpoint should be model.ckpt instead of model.ckpt.index.

[taol1]

The checkpoint should be model.ckpt instead of model.ckpt.index.

My 00.train/000/ directory is constructed as shown in the figure, no model.ckpt file.

model.ckpt is the prefix of files.
