# E0007 — WeightShapeMismatch

> The decoded weight array has a different number of values than the layer's declared dimensions.

<Warning>E0007: weight shape mismatch</Warning>

## What happened

The artifact declares a Dense layer with `in_features × out_features` weights, but the decoded base64 array has a different number of `f32` values.

## Why

The artifact is corrupt. The base64-decoded bytes decode successfully, but their length is inconsistent with the declared layer dimensions. Likely cause: truncated or modified artifact file.

## How to fix

1. **Recompile** from scratch: `thx.compile(model, "model.thx")`.
2. Verify artifact integrity: `thrindex doctor --check model.thx`. A CRC32 mismatch will accompany this error.

## Example

```
E0007: weight shape mismatch in layer 0: declared 358400 f32 values but decoded 1433596 bytes (358399 f32 values).
Why: the artifact's weight data is corrupt.
Fix: recompile the model from scratch.

```

## Notes

Each `f32` value is 4 bytes. If the decoded byte count is not divisible by 4, the error reports the byte count and the floor of `bytes / 4`.
