Hi Guys, I am trying to create a training, validation and test dataset in python for bike sharing dataset using Object oriented programming.

I have first created a method called "DATALOADER" to read the file and then split the data into train, validation and test set. However, I am facing some challenges while executing the code.

Pasting the code above and error response below. Need some help with that.

Error Message: **--------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-29-29ec681918b0> in <module> ----> 1 dataloader = Dataloader('C:/Users/pbhal/Downloads/hour.csv/hour.csv') 2 train, val, test = dataloader.getData() 3 fullData = dataloader.getFullData() 4 5 category_features = ['season', 'holiday', 'mnth', 'hr', 'weekday', 'workingday', 'weathersit']

TypeError: Dataloader() takes no arguments**

I was trying to create a train, validation and test set out of hour.csv datafile. However , it did not work out

CodePudding user response：

You have a typo, you should use __init__ (two underscores) instead of _init_. This means that your class does not have an initialization method defined, and the fallback (the Python class object I think) does not receive any argument.

You can validate that this is the issue with a small empty class:

class Example:
    pass

a = Example()  # Works
b = Example(1)  # Failes with "TypeError: Example() takes no arguments"
