# Core ML is not shipped for this model Core ML cannot export this model at all, so no `.pte` or `config.json` is published here. Use the XNNPACK or MLX build instead. ## Why The exporter exists in `export-scripts` for all four sub-models, but conversion fails on the first one (`duration_predictor`), tested 2026-08-20: ``` Placeholder val must be a tensor or fake tensor, but got type , value s16 + 1 ``` That is the Core ML dynamic-shape limitation hitting at **export** time rather than at execute. Every sub-model here carries dynamic dims (`T` for text 8..256, `L` for latent 4..1000), and a symbolic dim reaches the Core ML converter as a placeholder it cannot represent. `vocoder` takes only a float latent and was the best candidate of the four, but it is never reached: the run aborts on the first failure.
