No weights were successfully loaded from your weights file:

Error message

No weights were successfully loaded from your weights file: '{self._weights_file}'. Please check and try again.

What it means

Raised after the weight-transfer pass when loaded_ops == 0: the .keras weights file opened successfully, but not a single layer of the current model matched/successfully received weights from it. Faceswap treats total transfer failure as an error (partial mismatches only produce a warning with skipped_ops).

Solutions

1. Confirm the weights file was saved from the same model plugin and settings you are training now.
2. If you changed input size or other architecture-affecting settings, revert them to match the weights, or drop the weights file.
3. Check the log for the skipped-layers warning to see which layers failed and why (shape mismatch vs name mismatch).
4. If intentional (training from scratch), remove the load-weights option.

Example fix

# before: weights from a different model plugin
faceswap train ... -m mymodel -wm other_model_weights.keras

# after: either use matching weights
faceswap train ... -m mymodel -m same_arch_weights.keras
# or train fresh without -wm

# Before training, sanity-check that the weights model shares layer names with your model:
import keras.models as km
w = km.load_model(weights_file, compile=False)
my = km.load_model(state_file, compile=False)
shared = {l.name for l in w.layers} & {l.name for l in my.layers}
assert shared, "weights share no layers with this model; transfer will fail"

When it happens

Trigger: Loading a weights file whose architecture shares no layers with the current model — e.g. warm-starting from a different model plugin or a model trained with incompatible input size/settings, so every _load_layer_weights call returns 0.

Common situations: Trying to transfer weights between different model types; input dimensions or plugin settings changed so layer names/shapes never match; using a weights file saved by a much older version.
