Specs for chrono, cogview, flux2_klein, glm, hunyuandit, hyimage, joy,
kandinsky, longcat, nucleus, ovis, pixart and prx lived module-level in
model_<arch>.py. Move each into pipelines/<arch>/__init__.py to match
the layout used by anima, bria, ernie, f_lite, lens, qwen, step1x and
vibe.
Each model_<arch>.py now imports its spec lazily inside the load
function, so the package only gets pulled in when that arch is actually
loaded (kandinsky 2.x never goes through native dispatch and stays
untouched).
Also drop the "without this spec..." crash paragraph from the new
package docstrings plus ernie/__init__.py and bria/__init__.py.
ErnieImageTransformer2DModel has no from_single_file; selecting an
Ernie finetune in the UNET dropdown previously crashed with
"is not a valid JSON file" from from_pretrained.
Probe of jibMixErnie_v20.safetensors: 409/409 keys overlap with the
model state dict after stripping model.diffusion_model., zero missing
or unexpected. Spec is the minimum TransformerSpec(cls=...).
Adds pipelines/ernie/ernie_lora.py with try_load_lora/lokr/loha/oft
entry points modeled on the z-image native loader, wires it into
lora_load.load_safetensors, and adds 'ernieimage' to allow_native.
ERNIE attention is not fused (separate to_q/to_k/to_v/to_out.0), so
the loader skips the qkv-split machinery the z-image loader needs and
supports all four families uniformly. Recognized prefixes are
diffusion_model., transformer., and lora_unet_; PEFT lora_A/lora_B
keys are normalized to lora_down/lora_up. Verified against PEFT, LoKR,
and Kohya/AIT files in the wild with zero unmapped or shape-mismatched
modules.
