Based on the error message, I assume that you are missing sime preprocessing steps. separated floating-point numbers and we need to convert them and store in a list containing float numbers. 1 It would be helpful to show how you load and preprocess the data. The split() method splits a string into a list using a delimiter, separator.Įxample: Let’s discuss how to resolve a problem in which we have a. Hi, I am getting -ValueError: could not convert string to float while trying to generate a map via geographical coordinates.map() is a built-in method in Python that allows you to transform the items in an iterable without the need of an explicit for loop.Sometimes, while working with data, we could be dealing with decimal numbers. □ Solution 1: Using map() + split() + float() Whenever I try to run the algorithms on the datasets I get the following error 'could not convert string to float: S0' This error is produced during the during the evaluation of the 5 models Logistic Regression, Linear Discriminant Analysis, K-Nearest Neighbors, Classification and Regression Trees, Gaussian Naive Bayes and Support Vector Machines. Now that we know the reason behind the occurrence of this error, let’s dive into the solutions. When a numeric string contains non-special characters.When a numeric string contains a comma or other delimiters/special- characters.There are 2 major reasons that lead to ValueError: could not convert string to float while you try to use the float() method on a numeric string value. ValueError: could not convert string to float: ‘Max’Įxplanation: In the above example, num which contains a numeric text value was successfully converted to a floating-point number, while an error occurred at line 4, when you tried to convert a string that represents a normal text, which is not supported by the float() function in Python. File “D:/PycharmProjects/PythonErrors/rough.py”, line 4, in calling CrearMatriz could not convert string to float: calling CrearMatriz2 exception could not convert string to float: on field:: for line 0: : exception could not convert string to float: abc on field:abc: for line 2:3,abc,4 : exception could not convert string to float: on field:: for line 3: : CrearMatriz2()> 0.12, 30.2, 30.5, 22.0, 3.
