I tried the code in this CR, and unfortunately, I found that the loss does not decrease during training.

[xs1997zju]

Use the latest commit code, however after several iterations，the loss becomes NaN

[xs1997zju]

Just leave it?

[oahzxl]

this code is for experiment only. the updated code is in progress and will be released soon

[xs1997zju]

Is there a approximate release time？ Since the latest commit still contains bugs.

[TongLi3701]

We are still working on the pipeline. Once we validate the process, we will release.
