LightGCN and MF model are not working

[emrulhasan-nlp]

Describe the bug
I am trying to run some models. I have been able to successfully run ItemkNN, SLIMElastic, and BPR. However, when I want to run for LightGCN, it give the following error.

Error:
** Traceback (most recent call last):
File "/content/RecBole/run_recbole.py", line 46, in

File "/content/RecBole/recbole/quick_start/quick_start.py", line 52, in run
res = run_recbole(

model = get_model(config["model"])(config, train_data._dataset).to(config["device"])

self.norm_adj_matrix = self.get_norm_adj_mat().to(self.device)

A._update(data_dict)
AttributeError: 'dok_matrix' object has no attribute '_update'. Did you mean: 'update'?**

similarly for MF, I get the following error:
Error:
ValueError: model_name [MF] is not the name of an existing model.

Attached screenshot for both the errors. Thanks in advance
