![]() ![]() If the dimensionality of the data is not one-dimensional, change it accordingly, for example, change it to for two-dimensional. This function is better than np.loadtxt in that it can consider missing values, so the focus is on the latter. In this case, the number of columns used must match the number of fields in the data-type. ![]() numpy. If you dont need to do any type of numerical analysis, you can import the data as strings. If this is a structured data-type, the resulting array will be 1-dimensional, and each row will be interpreted as an element of the array. ValueError: could not convert string to float 3 Read csv or txt into list Similarly, we can also add the contents of a file into a Python: with open (filepath, 'r') as myfile: numberslst myfile.read ().split (',') print (numberslst) This will result in a Python list of strings. If you want to perform numerical operations on your data, youre going to need to remove the Time Freq header, and convert your times to numbers. But the solution that can be successfully solved is: data = np.genfromtxt('/data.txt', delimiter=',') Data-type of the resulting array default: float. I checked many blogs, The reason may be an extra character at the end, a space or something?Because my data is too long, the data file will get stuck when opened, so there is no verification if it is the reason. Although it is stored as str, it makes no sense to read it. The following example shows how to resolve this error in practice. Then the error reported is: ValueError: could not convert string to float: This error usually occurs when you attempt to convert a string to a float in pandas, yet the string contains one or more of the following: Spaces Commas Special characters When this occurs, you must first remove these characters from the string before converting it to a float. When reading, it is read like this: data = np.loadtxt('data.txt', delimiter=',') ![]() It is worth mentioning that it is saved like this when saving: with open('data.txt', 'a') as only:Īmong them, the format of data is a one-dimensional float list.

The problem might arise because of the meta-text in the. txt file that is not really written there but is copied when its content is loaded somewhere. Path = "C:\\Users\\Souro\\Downloads\\AXISBANK.csv" I think it is better to first import your text in an array or a string and then split it and save into the dataframe specifically when your data is not too large. Row = str(row).replace('\\', '') #deleting backslash ![]()
