How to re run fast-Dreambooth?

[BerryGoesNomad]

i run it before, everything goes smoothly, and then suddenly the connection is timed out
i tried to launch it again, follow every steps but it always fails

in Model download
it says "Skip this cell if you are loading a previous session that contains a trained model."
so i skipped that cell

in Dreambooth
i enter the last i used session name but it goes "Conversion error, if the error persists, remove the CKPT file from the current session folder"

and then i ignore that
so i go to next cell , in instance Images i run cell but i not upload anything because i uploaded the images last time i used , and then i go to next cell

when in Start DreamBooth
i press the box "resume training" and then i start the cell , and i not changing anything
but i got error
"Previous model not found, training a new model...
No model found, use the "Model Download" cell to download a model."

Please someone help me , what should i do?

You are running a cpu runtime not GPU

how can i change it? can u tell me please?

[TheLastBen]

Runtime -> Change runtime type -> GPU

[BerryGoesNomad]

thats looks like i got to pay for the GPUs, right?

[TheLastBen]

google does offer free GPU a few hours a day
