@akash97715 we have excellent documentation for the datasets library, which also includes how to load csv datasets. Please take a look there. Load — datasets 1.18.3 documentation
I am always happy to help when you run into issues, but reading documentation has never hurt anyone.
>>> data_files = {"train": "train.csv", "test": "test.csv"}
>>> dataset = load_dataset("namespace/your_dataset_name", data_files=data_files)
