The problem of upgrading to Torch 2.x arises from the DP mechanism in CTGAN, and seems to be the Opacus library itself being incompatible. I don't know yet how to fix this---if anyone wants to contribute to this, please reach out.

Thanks @bvanbreugel for opening this PR. We have been trying to use synthcity in our research, but the complex dependencies with old versions of PyTorch and Python is a nightmare. That's a shame.

Have you been able to make it work? Opacus 1.4 works with PyTorch 2.0 apparently.

Any updates on this?

We're also very interested to let synthcity support PyTorch 2.x

The dependency requirements have now been updated in #288
