Hi, eveyone.

I am using the solution for tuning hyperparams in my project as described in this video [Tuning Hyperparameters Using Grid Search and Random Search with DVC - YouTube](https://www.youtube.com/watch?v=W48Tvx2p-xE).

Sometimes I get a message with error during adding experiments in queue.

> ERROR: unexpected error - [WinError 5] Отказано в доступе: ‘D:\GD Anton\dev\data\04.dvc\…\.git\index.lock’ → ‘D:\GD Anton\dev\data\04.dvc\…\.git\index’

Finally a queue with experiment created and I can start them. Can this error influence on something imoprtant?
