URL: https://github.com/apache/tvm/issues/17578
I am trying to compile ONNX model using Apache TVM to target MIPS platform.
Here is how my code looks like:
```
import tvm
from tvm import relay
from tvm.contrib import graph_executor
import torch
import onnx
input_shape = (1, 200, 10)
onnx_model = onnx.load("model.onnx")
# Convert to Relay
input_name = "input0"
shape_dict = {input_name: input_shape}
mod, params = relay.frontend.from_onnx(onnx_model, shape_dict)
# Target MIPS
target = "llvm -mtriple=mips-linux-gcc"
# Compile the model
with tvm.transform.PassContext(opt_level=3):
lib = relay.build(mod, target=target, params=params)
# Save the model artifacts
lib.export_library("deployable_model.so")
with open("deploy_graph.json", "w") as f:
f.write(lib.get_graph_json())
with open("deploy_params.params", "wb") as f:
f.write(relay.save_param_dict(lib.get_params()))
```
However, it gives me following exception:
```
$ python onnx2tvm.py
[00:33:25] /workspace/tvm/src/runtime/threading_backend.cc:338: Warning:
more than two frequencies detected!
One or more operators have not been tuned. Please tune your model for better
performance. Use DEBUG logging level to see more details.

TVMError:
---------------------------------------------------------------
An error occurred during the execution of TVM.
For more information, please see: https://tvm.apache.org/docs/errors.html
---------------------------------------------------------------
Check failed: (target_machine_ != nullptr) is false: No available targets
are compatible with triple "mips-linux-gcc"
```
It seems that `mips-linux-gcc` target is not supported. I also tried
`mips-linux-gnu`, which also did not work.
What is target string for mips target?
