@Vinaysukhesh98 how fix it ??? i get the same issue

[Kaneki-x]

@SwordFishKe @Vinaysukhesh98 You can add a check for args.size() == 21, and set the args[21] parameter to nullptr within the method to temporarily bypass this issue. Preliminary analysis suggests that the additional parameter in this method modified the condition for checking the number of parameters, but the places that call this method externally did not add the new parameter, resulting in a mismatch between the old and new number of parameters. It seems that the developers of TVM do not pay attention to or test the actual performance of the MLC-LLM client, as crashes often occur after changes are made.

[Kaneki-x]

@vinx13 suspect that the crash issue was caused by your 8059c770dc563411717a44d9409888be3f85b7ee commit change on September 4th. Can you help take a look and fix it?

[vinx13]

Did you checkout the updated the TVM submodule? You also need to re compile the model

[Kaneki-x]

yes, the tvm submodule is update to e0ef1c92add4048823a5e2c8724495418865986b, and clean up all build cache. then try mlc_llm package in MLCChat folder, after compile and install still get same crash stack. Please check if there are any missing operations.

[vinx13]

@MasterJH5574 seems the submodule already contained the fix for missing func for TIR kv cache. Anything missing?

[MasterJH5574]

Could you folks try run with environment variable MLC_JIT_POLICY=REDO to force the recompilation of models? For example, MLC_JIT_POLICY=REDO python -m mlc_llm package.

The submodule update won't automatically trigger recompilation unfortunately, and we will try our test to make things stable.

[Vinaysukhesh98]

Hi @MasterJH5574 ,
I tried rebuilding and did below changes in android code to come here.

Seems the error is due to the gradle version and android version mismatch i gave a temp fix by updating the gradle to 8.7 and adding the android:enableOnBackInvokedCallback="true" to the android xml file but i still sees the different behaviour where attaching log below model is phi-3

where it is giving very poor prefill tokens that need to be fixed in the code it seems

@MasterJH5574 I cleared the build cache, then executed the new command you provided in the MLCChat directory, and recompiled and ran it, but the same error still occurred. I would like to ask where the problem lies.

[yoghur]

I met the same problem when i adding new quant method and compile it

org.apache.tvm.Base$TVMError: TVMError: Check failed: (args.size() == 22 || args.size() == 23) is false: Invalid number of KV cache constructor args.

but the app worked well when using the model quantized by q4f16_1

Does this error have anything to do with the new quantization method I added?

even the app working well did you observe the prefill tok/sec is too worse in this.

[MrRace]

Same problem！when use Qwen2！But for Qwen1.5, it can work！
