Subject [TVM Discuss] [Development] [Relay][ONNX] KeyError: 'W' when compiling from onnx
Date Fri, 05 Apr 2019 05:47:02 GMT


The following error occurs when I try to compile an onnx model. From what I can tell using
[Netron](https://lutzroeder.github.io/netron/), there is an input `W`. However, it's not another
node but instead some (static) initialization data for the current node.

The model can be downloaded here (md5: 2c4009c79e2a5b62d8a3fef14f1fc03b): https://we.tl/t-5E4oXO0Rmq

```python
  File "/home/martin/Dev/xyz/src/tvm/compile_model.py", line 79, in compile_model
    relay_func, params = relay.frontend.from_onnx(onnx_model, shape=input_shape_dict, dtype=input_dtype_dict)
  File "/home/martin/.local/lib/python3.6/site-packages/tvm-0.6.dev0-py3.6-linux-x86_64.egg/tvm/relay/frontend/onnx.py",
line 1126, in from_onnx
    sym, params = g.from_onnx(graph, opset)
  File "/home/martin/.local/lib/python3.6/site-packages/tvm-0.6.dev0-py3.6-linux-x86_64.egg/tvm/relay/frontend/onnx.py",
line 942, in from_onnx
    inputs = [self._nodes[self._renames.get(i, i)] for i in node.input]
  File "/home/martin/.local/lib/python3.6/site-packages/tvm-0.6.dev0-py3.6-linux-x86_64.egg/tvm/relay/frontend/onnx.py",
line 942, in <listcomp>
    inputs = [self._nodes[self._renames.get(i, i)] for i in node.input]
KeyError: 'W'
```
