It seems as recent versions of `trezor` don't work with python 2.x:
```
/build/trezor-0.9.1/dist /build/trezor-0.9.1
Processing ./trezor-0.9.1-py2-none-any.whl
trezor requires Python '>=3.3' but the running Python is 2.7.15
builder for '/nix/store/aqyxki0ckanjk4r1f0an4kj1w4s3kk4f-python2.7-trezor-0.9.1.drv' failed with exit code 1
cannot build derivation '/nix/store/gp4smkzc9r87lzajs17jnq4rh2ayc5q0-python2.7-keepkey-4.0.0.drv': 1 dependencies couldn't be built
```
The package is currently broken and most folks recommend to use
`flask-caching` (see
https://github.com/thadeusb/flask-cache/issues/171).
The only package in `nixpkgs` which remained to use `flask_cache`
(`graphite_api`) still builds with `pythonPackages.flask-caching`.
The removal and corresponding `graphite_api` change unbreaks several
Hydra builds (see https://hydra.nixos.org/build/76953777).
tdesktopPackages.preview: 1.3.7 -> 1.3.10
Without the patch the build will fail with the following error:
