Override .ckpt in ModelCheckpoint Callback

[victkid]

Hi,

I'm using ModelCheckpoint Callback to save my model checkpoint. pytorch lightning automatically attaches -v0, -v1 to the filename I specified if it finds checkpoint models exist in dirpath. Instead of saving all the models from different runs, is there a way to make the ModelCheckpoint Callback only save one model in the checkpoint folder and just override the model from previous runs?

For example, my ModelCheckpoint is as follow:

ModelCheckpoint(monitor='valid_score',
                              dirpath="./checkpoint/",
                              filename="model",
                              mode='max', save_top_k=1))

If I run the code for 3 three times, my checkpoints folder will have the following:

- checkpoint:
    - model.ckpt
    - model-v0.ckpt
    - model-v1.ckpt

Would it be possible to just have model.ckpt in my checkpoint folder no matter how many times I run the code?

We don't support this, but you could always remove the file manually between runs with os.remove()
