error in HetGNN_sampler.py

[Kingrd97]

line 168, in assign_features_to_blocks
assign_simple_node_features(blocks[0].srcdata, g, ntypes)
AttributeError: 'dict' object has no attribute 'srcdata'

[Kingrd97]

seems the academic4HetGNN dataset and hetgnn_sampler.py does not match

[Theheavens]

Could you show more information, about errors and which experiments you run?

[Kingrd97]

The environment is installed according to the steps in README，CPU version of Pytorch & DGL

python main.py -m HetGNN -t node_classification -d academic4HetGNN -g -1

[Theheavens]

I'm not sure that whether you use the latest codes. You can try to clone the openhgnn again.

[Kingrd97]

I've pulled on the main branch. It's the latest

[Theheavens]

Does this error still exist? We have tested it without any errors.

[Kingrd97]

Yes, similar error occurs when runing "python main.py -m HeCo -d acm4HeCo -t node_classification -g -1".
Other models seems work well

File "/home/openhgnn/OpenHGNN/openhgnn/models/HeCo.py", line 58, in build_model_from_args
if args.meta_paths is None:
AttributeError: 'Config' object has no attribute 'meta_paths'

after I fixed it, there are still some problems following

File "/home/openhgnn/OpenHGNN/openhgnn/trainerflow/HeCo_trainer.py", line 48, in preprocess
self.preprocess_feature()
AttributeError: 'HeCoTrainer' object has no attribute 'preprocess_feature'

This func hasn't been realized yet?

[Theheavens]

Sorry, it's a bug. I fixed it right now.

[Kingrd97]

Hope you can check the data of HetGNN. There is always AttributeError with dataloader no matter which version of torch is used

[Theheavens]

We check the AttributeError you mentioned. It is an error raised by the API modification of DGL with the nightly build version.
We will check the new API and fix the bug. Before that, we recommend that uninstall the dgl of nightly build version and install the stable version.
Run this to install:
conda install -c dglteam dgl-cuda10.1 or pip install dgl-cu101 -f https://data.dgl.ai/wheels/repo.html.
