How to Load Data From a csv using Numpy

 

Numpy is a powerful library in Python for working with numerical data. One of the ways to load data into a Numpy array is by reading it from a CSV (Comma Separated Values) file.

To load data from a CSV file using Numpy, you can use the numpy.genfromtxt() function. This function allows you to specify the file path and the delimiter used in the CSV file. You can also specify the data type of the columns and any missing values.

Once the data is loaded, it will be stored in a Numpy array, which is a powerful data structure that allows you to perform various operations on the data, such as mathematical calculations, sorting, and indexing.

It’s important to note that, before loading the data, you need to make sure that the csv file is in the correct format, including the correct delimiter, correct data type and correct missing values.
