Errors occur while calling NodePropPredDataset in dataset.py

I can run your code correctly on small dataset by using scripts in run.sh and get similar results within the paper but when I'm trying to reproduce nodeformer on large graph dataset, it comes out an error on both amazon2m and ogb proteins dataset.

Traceback (most recent call last):
  File "main-batch.py", line 43, in <module>
    dataset = load_dataset(args.data_dir, args.dataset, args.sub_dataset)
  File "/home/workspace/NF/NodeFormer/dataset.py", line 102, in load_dataset
    dataset = load_amazon2m_dataset(data_dir)
  File "/home/workspace/NF/NodeFormer/dataset.py", line 308, in load_amazon2m_dataset
    ogb_dataset = NodePropPredDataset(name='ogbn-products', root=f'{data_dir}/ogb')

    additional_node_files = self.meta_info['additional node files'].split(',')
AttributeError: 'float' object has no attribute 'split'

This error occurs in dataset.py while calling the NodePropPredDataset functiuon :

NodeFormer/dataset.py

Line 290 in 64d2658

ogb_dataset = NodePropPredDataset(name=name, root=f'{data_dir}/ogb')

NodeFormer/dataset.py

Line 306 in 64d2658

ogb_dataset = NodePropPredDataset(name='ogbn-products', root=f'{data_dir}/ogb')

I tried to fix this error and ran into the implementation of NodePropPredDataset by changing the 'float' object into 'str':

additional_node_files = str(self.meta_info['additional node files']).split(',')

It passed, but another error comes out ：

Loading necessary files...
This might take a while.

I don't know what‘s happening...... If you need more information, please let me know.

Hi, have you checked the environement packages are all consistent with the requirement.txt? And, did you use your own preprocessed ogb data or the data downloaded by the codes. The error seems that the version of the loaded ogb datasets is inconsistent with the environment where the code is running

I ran the code in anaconda and I use conda list checked that the environment packages are all consistent with the requirement.txt. But the terminal remind me that ：

WARNING:root:The OGB package is out of date. Your version is 1.3.1, while the latest version is 1.3.6.

Is this what you mean ’the version of the loaded ogb datasets is inconsistent with the environment where the code is running‘?

I use the dataset downloaded by the codes.

I see, have you tried removed the preprocessing files under the files of the ogb dataset and run the code again? It could be caused by the inconsistent version of the preprocessed fileds.

Also, you can check the correctness of the dataset path '../data//ogb/ogbn_proteins/raw/nan.csv.gz'. It seems there is a redundant '/'

Thank you for your quick response.

you mean only leave the files in raw folder? I tried remove files in other folders except 'raw', but the same error still occurs below.
Btw, I'm currently using the fix method aforementioned at the beginning: 'changing the 'float' object into 'str' in NodePropPredDataset functiuon' , and I still don't know if that's the right thing to do.
About the redundant '/'

The dataset path is correct for small graph dataset, and I didn't change the floder's path while running the large graph script, cuz the whole process is done automatically.

Do you have any idea about the file named 'nan.csv.gz' ? I can't find it in the dataset I downloaded.

Hi, sorry for the late response due to the paper submission ddl. I think there might be some issues in your ogb package version. I just checked the files under my data file folder and it does not contain nan.csv.gz

./ogb/ogbn_proteins/raw

./ogb/ogbn_proteins/processed

Thank you for your suggestion. I will further find out what causes bug and get back with an update comment once I've resolved the issue in a few days.

Good luck for your new paper!

Thank you and hopefully you can find the bug soon.

I tried to setup the enviroment again with ogb1.3.1 and I successfully ran your code on ogbn-proteins and amazon2m. It's weird that last time I time I setup on a WSL environment but failed with ogb1.3.1, so this time I tried on a linux one, not sure whether it's the reason. Anyway, thanks to your suggestions.

Btw, I meet a few troubles when I setup again. And I have a suggestion that if someone is in trouble with the installation of torch geometric/sparse/scatter, you can try installing in order torch_scatter==2.0.7,torch_sparse==0.6.10,torch_geometric==1.7.2.

Again, thank you for your help!

Glad to hear that you resolved the issue! Indeed, the installation of the PyG package is dependent on the torch_scatter and torch_sparse. And, the versions of these packages should stay strictly consistent, otherwise there could be some wired bugs.
