Are the uncommit changes in un-tracked files ?
In other words: clearml will only save uncommited changes from files that are tracked by your local git repo

They are actually from tracked files. Actually, I get the uncommitted changes under Execution tab.

But, it uses the committed changes instead of these values.

-    batchsize: 22
+    batchsize: 4

I see that under Executed . But, the batch size for me is 22 under Configuration/General

Another very related question is, does uncommitted changes work for sub modules as well? I mean, when there is a directory from a different repository cloned as a submodule.

Looks like your issue is not that ClearML is not tracking your changes but more about your Configuration is overwrriten.
This often happen to me. The way I debug this is put a lot of print statement along the code to track when the Configuration is overwriten and narrow down why. print statement will show up in the Console tab.

I commited the uncommited changes and tried it. It works. The batchsize becomes 4.

I don't use submodule so don't really know how that behave with ClearML

Okay. thanks. But, about the overriding, I tried committing and when commited it works. So, I think that means the configuration is not overriden else where.

I can only guess with little information here. You better try to debug with print statement. Is this happening in submodule uncommited changes ?
