Issue with SubgraphLoader() and/or Torch

[ersanchezo]

Hi, I obtained this error by just running the first example train_gcn.py

Traceback (most recent call last): File "/home/ersa/spage2vec/pyg_autoscale/examples/train_gcn.py", line 85, in train(model, loader, optimizer) File "/home/ersa/spage2vec/pyg_autoscale/examples/train_gcn.py", line 57, in train for batch, *args in loader: File "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch/utils/data/dataloader.py", line 633, in next data = self._next_data() File "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch/utils/data/dataloader.py", line 677, in _next_data data = self._dataset_fetcher.fetch(index) # may raise StopIteration File "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch/utils/data/_utils/fetch.py", line 54, in fetch return self.collate_fn(data) File "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch_geometric_autoscale/loader.py", line 74, in compute_subgraph rowptr, col, value, n_id = relabel_fn(rowptr, col, value, n_id, File "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch/_ops.py", line 502, in call return self._op(*args, **kwargs or {}) RuntimeError: isBool() INTERNAL ASSERT FAILED at "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch/include/ATen/core/ivalue.h":666, please report a bug to PyTorch.

Thanks for reporting. What does

import torch
import torch_geometric_autoscale
relabel_fn = torch.ops.torch_geometric_autoscale.relabel_one_hop

rowptr = torch.tensor([0, 2, 3])
col = torch.tensor([0, 1, 0])
value = torch.tensor([0, 1, 2])
n_id = torch.tensor([0, 1])

relabel_fn(rowptr, col, value, n_id, True)
relabel_fn(rowptr, col, value, n_id, False)

return for you?

It returned this: File "/home/ersa/spage2vec/trial_run/troubleshoot.py", line 10, in "module" relabel_fn(rowptr, col, value, n_id, True) File "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch/_ops.py", line 502, in call return self._op(*args, **kwargs or {}) RuntimeError: isBool() INTERNAL ASSERT FAILED at "/home/ersa/miniconda3/envs/spage2vec/lib/python3.10/site-packages/torch/include/ATen/core/ivalue.h":666, please report a bug to PyTorch.

Can you show me the installation log when running python setup.py install? Looks like something went wrong during installation.

[ersanchezo]

I accidentally deleted my conda environment, but was able to install it correctly with stable CUDA/Torch combination. Thanks for the help!

I had installed an unstable version combination of CUDA and Torch and was fix restarting my conda environment. Thanks for the help!
