Why do I get mse=0.91 for the MSLR dataset using DANets?

I download the code+date from your github, but get mse=0.91, not 0.55.
There is some codes I debug:
(1) in data_util.py, add '.txt'
def svm2pkl(source, save_path):
before:
X_train, y_train = load_svmlight_file(os.path.join(source, 'train'))
X_valid, y_valid = load_svmlight_file(os.path.join(source, 'vali'))
X_test, y_test = load_svmlight_file(os.path.join(source, 'test'))
after:
def svm2pkl(source, save_path):
X_train, y_train = load_svmlight_file(os.path.join(source, 'train.txt'))
X_valid, y_valid = load_svmlight_file(os.path.join(source, 'vali.txt'))
X_test, y_test = load_svmlight_file(os.path.join(source, 'test.txt'))
(2)in deault.py, add 'cfg.fit.weight_decay = 1e-5','cfg.fit.schedule_step = 20'.
As I do regression task, when I run main.py, the Keyerror: weight_decay ,Keyerror: schedule_step .I can't find these two parameters define in deault.py ,MSLR.yaml, main.py, so I add 'cfg.fit.weight_decay = 1e-5','cfg.fit.schedule_step = 20' in deault.py.
(3)Run codes by using python predict.py -d [dataset_name] -m [model_file_path] -g [gpu_id] where the best.pth path is already specified. I don't get the mean: Replace the resume_dir path with the file path containing your trained model/weight. Does it mean set the resume_dir path to the best.pth path?

Thank you for your interests. The results may fluctuate slightly, but not by such a large margin.

Maybe you forgot to pre-process the data?

Maybe you did not train the model before inference?

You may check this two aspects first.
