Your forecasting system used 13 levels instead min where g = 9.8065 m/s^2 is the gravitational acceleration R = 287.04 is gas constant for air Tv [K] = T [K]...

Undersurface values

Some values on p-levels coresponds to the virtual values under Earth surface May be we dont takes into account this values in loss function ?

The Climate Forecast System (CFS) is a climate model with maximum lead time 7392 hours updated every 6 hours His output forecasting data available at https://nomads.ncep.noaa.gov/pub/data/nccf/com/cfs/prod https://noaa-cfs-pds.s3.amazonaws.com/index.html https://planetarycomputer.microsoft.com/dataset/storage/noaa-cfs Are you...

**Describe the bug** I using the function with ti.ad.no_grad decorator but taichi engine creates gradients tensor (on forward pass!!) **To Reproduce** ```py import torch device = 'cuda' import taichi as...

**Describe the bug** If I using ti.ad.no_grad decorator the returns replaces to None **To Reproduce** ```py import torch device = 'cuda' import taichi as ti ti.init(getattr(ti,device)) ti2d = ti.types.ndarray(ndim=2, needs_grad=False)...

**Concisely describe the proposed feature** I'm trying to use Taichi to speed up traceformers-like neural network. I encounter float16 type overflow and have to use float32 where it is not...
