Constructor __init__ is written to take two position arguments, but when used, reports the error tha-CodePudding

I have a class and constructor I'm working on, and I added an extra parameter to __init__, and now I get the error, TypeError: FeatureDataset() takes 1 positional argument but 2 were given.

I wonder why. It seems to me that it should accept two arguments. It's an incomplete function, but I'd like to get past this constructor argument number error. I have checked several answers and either they were about something specifically different, or indentation, and I have neither of those issues (4 indents per new indentation divide).

def FeatureDataset(Dataset):

    def __init__(self, root_dir, file_name):

        #load csv
        self.file_out = pd.read_csv(file_name)
        self.root_dir = root_dir
        self.labels = self.file_out.iloc[1:160, 0].values
        self.features = self.file_out.iloc[1:160, 1:].values

        #Feature Scaling
        sc = StandardScaler()
        label_train = self.labels
        feature_train = self.features #sc.fit_transform(features)

        #Convert to torch tensors
        self.feature_train = torch.tensor(label_train, dtype = torch.float32)
        self.label_train = torch.tensor(label_train)

file_name = "data.csv"
root_dir = "archive"
feature_set = FeatureDataset(root_dir, file_name)

CodePudding user response：

This defines a function, not a class:

def FeatureDataset(Dataset):

... try ...

class FeatureDataset(Dataset):
