petersktang opened a new issue, #19678:
URL: https://github.com/apache/tvm/issues/19678
### Expected Behaviour: dlopen libtvm_compiler.so
loading succesful
### Actual Behaviour: dlopen libtvm_compiler.so failed with undefined symbols
libtvm_compiler.so is built with undefined symbols, failing
ctypes.CDLL("libtvm_compiler.so")
```
