@abaranov25 seems like Chronos2 pipeline did not work well on S-1 example, do you have an idea why? I'm curious if you use S-1-test would you get different results?

I'm curious why 256? Orion pipelines that are forecast based are usually set to 250. For timesfm, it was set to 256 because it needs to be a multiple of 32 according to their docs.

We typically set the example to interval=21600 since our example code uses NASA signals (MSL and SMAP)

If chronos works on python 3.9+ remove this comment completely

add chronos to setup.py under the pretrained_requires section, then remove the try-catch since it will always be installed using pip install orion[pretrained]
