Google Colab using T4 gpu and any other gpu - still the same error when I tried to train my model

hi friend, I occur the same error, have you solved it, thank you sincerely if you can help

It's not fixed yet but I found workaround. After you make environment and clone git of Fish-Diff into your colab you have to change config file in fish because google colab doesn't use bfloat16 so it has to be changed (for now as a quick solution). Here is the file directory: /content/fish-diffusion/configs/base/trainers/base.py

in this file change line 18 from 'precision="bf16-mixed",' to 'precision="16-mixed",' and save it. It should work now.

thank you very much for your help, it works now. Look forward to discussing with you about the effects of the model Sincerely yours!

dear friend, this code can fine-tune text encoder projection layer + diffusion or fine-tune hifigan, but have you fine-tuned contentvec using this code? such as use different layers' transformer in contentvec to cut size

thank you sincerely for your help
