# Piscis ps_20240419_112256

PyTorch conversion of the legacy Piscis JAX checkpoint
[`wniu/ps_20240419_112256`](https://huggingface.co/wniu/ps_20240419_112256),
for Flax-free inference in NimbusImage's Piscis Predict and Train workers.

## Conversion validation

The Piscis 1.0.0 JAX-to-PyTorch converter was first validated against the
published `20230905` JAX and PyTorch checkpoint pair. All 583 tensors matched
exactly in key, shape, dtype, and value; the maximum absolute difference was
`0.0`. The same validated converter produced this checkpoint.

- Source checkpoint SHA-256: `28fea47454c108dac5e2899f5c4f84fd489792f28fbd5d6b3e002236516952e2`
- Converted checkpoint SHA-256: `f281a239d1d5075ee2342c4772ba7167c441f878e5345c632436caf3b43d320a`
- Converted checkpoint size: `30,083,712` bytes
- State dictionary: 583 tensors
- Metadata: `adjustment=standardize`, `input_size=(256, 256)`, `dilation_iterations=1`, `channels=1`
