The error above occurs after updating the git of mlc-llm.

However, I have no idea how to resolve this. Please provide me with a solution and ideas.

I found a problem.

https://llm.mlc.ai/docs/deploy/android.html#

The link requested 'export TVM_HOME=... #TVM Unityruntime', but this is not how it should be set.

It should be set to 'TVM_HOME = mlc-llm\3rdparty\tvm'. I would appreciate it if you could revise it. @MasterJH5574

Thank you @Moon-Ahn for reporting.

The link requested 'export TVM_HOME=... #TVM Unityruntime', but this is not how it should be set.

I'm still trying to understand what you described. Could you point me the exact position where the documentation page does this export?

@MasterJH5574

https://llm.mlc.ai/docs/deploy/android.html#

TVM_HOME so that its headers are available under $TVM_HOME/include/tvm/runtime.

export TVM_HOME=...     # TVM Unity runtime

From the two settings, I think the user can be confused.

In fact, in my previous version of mlc-llm, I set it to 'TVM_HOME = mlc-llm/3rdparty/tvm/include/tvm/runtime' and it worked fine.

I got an error after updating the mlc-llm version, and I fixed the issue by changing the configuration to 'TVM_HOME = mlc-llm_path/3rdparty/tvm/'.

If the information I gave you is incorrect, please ignore it. Thank you.
