TFLite Model Structure Viewer failed or looks wrong? Troubleshooting guide
Troubleshoot extensions, file structure, dependencies, encoding, memory, and output error in TFLite Model Structure Viewer while preserving the source.
Preserve the source first
Do not rename and overwrite the original, and do not treat a browser preview as the only acceptance record. Use a small copy and record size, producer, version, browser, and exact error.
The easy-to-miss fact for this format
For an int8 classifier with input [1,224,224,3], inspect dtype, scale, zero point, and operator versions. Valid structure does not prove complete NNAPI delegate support.
Recommended troubleshooting order
- Test the page example or a smaller known-good file to confirm the tool runs.
- Check extension, signature, companion files, remote URL, and CORS; exclude a downloaded HTML error page.
- Supply the input again according to the workflow:
- Choose a .tflite or .lite file.
- Inspect schema, subgraphs, inputs, outputs, and operator versions.
- Review tensor dtype, shape, buffer, scale, and zero point.
- Record custom ops and dynamic shapes for target-device validation.
- Close memory-heavy tabs and retry in current Chrome or Edge.
- If it still fails, re-export from the producing application and validate in the receiving system.
Common questions and answers
Can it prove NNAPI support?
No. Device, Android release, and delegate operator support must be tested.
How do I inspect quantization?
Review dtype, scale, and zero point on input, output, and weight tensors.
Is the model uploaded?
Processing runs in this browser tab; the file is not uploaded to FreeTool to perform the task.
Limits that must not be bypassed
- No inference or delegate compatibility test
- Custom ops expose names and references only
- No model accuracy, latency, or peak-memory prediction
