出现No module named 'torch_extension'的错误通常是由于缺少torch的扩展模块导致的。可以尝试以下几种方法来解决这个问题:
1. 确认是否正确安装了torch和相关扩展模块。可以使用以下命令来安装torch和扩展模块:
```shell
pip install torch
pip install torch-scatter -f https://pytorch-geometric.com/whl/torch-1.9.0+cpu.html
pip install torch-sparse -f https://pytorch-geometric.com/whl/torch-1.9.0+cpu.html
pip install torch-cluster -f https://pytorch-geometric.com/whl/torch-1.9.0+cpu.html
pip install torch-spline-conv -f https://pytorch-geometric.com/whl/torch-1.9.0+cpu.html
```
2. 确认是否正确设置了环境变量。可以使用以下命令来设置环境变量:
```shell
export C_INCLUDE_PATH=/path/to/your/cuda/include:$C_INCLUDE_PATH
export CPLUS_INCLUDE_PATH=/path/to/your/cuda/include:$CPLUS_INCLUDE_PATH
export LD_LIBRARY_PATH=/path/to/your/cuda/lib64:$LD_LIBRARY_PATH
```
3. 确认是否正确编译了扩展模块。可以使用以下命令来编译扩展模块:
```shell
python setup.py build_ext --inplace
```
