Dvc: DVC is busy and locked

[MathieuMarauri]

Hello,

I am trying DVC and it looks really promising so far, thanks for the good work.

I am having an issue I can't seem to be able to fix, whatever the dvc command I run I am having the following error:

ERROR: failed to obtain data status - cannot perform the cmd since DVC is busy and locked. Please retry the cmd later.

What can I do? I even tried completely restarting my computer.

Cheers,
Mathieu

If no dvc processes are running you can simply remove the lock file, which is .dvc/lock. This is a known issue of bad error message, which is already fixed, but not released yet.

BTW, how do you get to this state?

Hello,

Thank you for your help. I was trying to run a dvc run command but as things were too slow (from the train code I was using) I exited the command and closed my computer. When I worked again on this project, I got stuck with the error.

Cheers,

@efiop Do you think we should implement some general logic to remove the lock on KeyboardInterrupt? On the other side, without knowing what process created it, we risk removing the lock that was not created by the interrupted command.

@pared Hm, does it not remove itself on KeyboardInterrupt? 🤔

@efiop sorry, you are right, seems like `lock.__del__`` is taking care of lock file deletion.

Hi, I actually had the same problem.
I deleted the tmp/rwlock as well, and it solved the problem.
