Description
🐛 Describe the bug
A simple slice assignment called inside a module causes a floating point exception when the module is exported into the ONNX via torch.onnx.export.
- The full error message on a Ubuntu server is
Floating point exception (core dumped). - Note that I was able to reproduce this behavior only on the Ubuntu server. The behavior on Macbook M1 Pro was just a few warning messages without failure. See the last section for more details.
The code for reproducing the error
Let's call it repro.py
import io
import torch
class SliceAssignZeros(torch.nn.Module):
def forward(self, x: torch.Tensor):
x[1:-1] = 0
return x
def main():
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('-s', '--size', type=int, default=2)
args = parser.parse_args()
x = torch.ones(args.size)
model = SliceAssignZeros()
print(f'input: {x}')
print(f'output: {model(x)}')
with io.BytesIO() as f:
torch.onnx.export(model, (x, ), f)
if __name__ == '__main__':
main()Steps to reproduce
1. Set up environment
See the details about the environment in the Versions section.
conda create -n issue python=3.10 -y
conda activate issue
conda install pytorch -c pytorch -y
pip install onnx
2. Run the following command
python repro.py -s 2
NOTE: If you give any positive integer value to other than 2 to the -s flag, the script runs normally.
The Output
In my opinion, expected behavior are:
- the model is exported into ONNX normally; or
- torch warns (or throws an exception) with message indicating that the index range used for slice assignment is empty.
However, the error message on Ubuntu wasn't helpful to find out the root cause of the core dump. (Empty slice assignment doesn't look very relevant to floating point exception in my opinion.)
It was nice that the code worked on MacOS, but the warning message was still not very helpful.
Ubuntu 22.04
input: tensor([1., 1.])
output: tensor([1., 1.])
Floating point exception (core dumped)
MacOS Ventura 13.4.1
input: tensor([1., 1.])
output: tensor([1., 1.])
