Hi, is there any appetite to get this finished off? If so I could devote some time to it. Thanks!

@sanket-kamthe thanks for this! I look forward to studying that in the next week or so when I can!

Hard to know without the code but I guess you are passing something which is float64 to the local linear trend and day of the week effects, then either nothing...

@martin-wiebusch-thg I think this is due to gradients with `tf.gather` returning an `IndexedSlices` rather than the expected tensor, see e.g. https://www.tensorflow.org/api_docs/python/tf/IndexedSlices It's possible to convert to tensor using `tf.convert_to_tensor` however...

@a-jp I was wondering where you got to with this? Did you see the Hessian C code in the link in this issue? https://github.com/EnzymeAD/Enzyme/issues/1123 Thanks.
