What resources can you use to train models for free?

Today I tried fine-tuning the model for summarization (from the guide), but after a while (maybe an hour) the code crashes without an error (like process finished with code -41414).
I don’t have a powerful PC and don’t have money to rent servers for training, so I would like to know options from experienced users

What’s the hardware you used?

i7-4770 CPU and ~26gb ram
no cuda because i have only 4gb vram

perhaps the trainer tried to allocate more ram than was provided. I have now launched a script for training, peak consumption is ~22gb ram (only python and task manager open). I’ll leave this for a while and see what happens
