I'm working with 'SpeechRecognition' demo app, and I got the same error message 🥲

https://github.com/pytorch/android-demo-app/issues/202#issuecomment-972664735 This (in issue #202) worked for me. hope it helps :)

I fix it by adding changing dependencies to implementation 'org.pytorch:pytorch_android_lite:1.10.0'

The torch.jit.mobile has a _backport_for_mobile function to "backport" a model to a given version

from torch.jit.mobile import (
    _backport_for_mobile,
    _get_model_bytecode_version,
)

MODEL_INPUT_FILE = "model_v7.ptl"
MODEL_OUTPUT_FILE = "model_v5.ptl"

print("model version", _get_model_bytecode_version(f_input=MODEL_INPUT_FILE))

_backport_for_mobile(f_input=MODEL_INPUT_FILE, f_output=MODEL_OUTPUT_FILE, to_version=5)

print("new model version", _get_model_bytecode_version(MODEL_OUTPUT_FILE))

this lines solve model version issue But I facing similar error like below logcast

errorinas

please anyone give solution about issue ... thanks in advanced.

@NeighborhoodCoding Hello. Were you able to fix the issue? If yes, can you please share your experience what did you modify. Thanks a lot in advance!

NeighborhoodCoding commented 1 year ago

It's git source is updated about 6 month ago, and I noticed the problem is solved.

I am getting, Duplicate Class errors if i change version to any version than existing. How to resolve this issue?
