The problem might arise because of the meta-text in the. ValueError: could not convert string to float: âoid sha256:xxxxâ The above exception was the direct cause of the following exception: Traceback (most recent call last): File helmholtz.py, line 72, in run openfoamvar csvtodict (toabsolutepath (validation/helmholtz. txt file that is not really written there but is copied when its content is loaded somewhere. I am trying to retrieve the number of rows and columns from the data set and I have entered the following: import os import numpy as np import pandas as pd im. 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. If the dimensionality of the data is not one-dimensional, change it accordingly, for example, change it to for two-dimensional.Row = str(row).replace('\\', '') #deleting backslash This function is better than np.loadtxt in that it can consider missing values, so the focus is on the latter. But the solution that can be successfully solved is: data = np.genfromtxt('/data.txt', delimiter=',') 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. In this case, the number of columns used must match the number of fields in the data-type. 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. Then the error reported is: ValueError: could not convert string to float: Data-type of the resulting array default: float. There are two ways to deal with this: firstly, you can set the data type argument dtype equal to str (for string). import numpy numpy.loadtxt ('data.txt', delimiter'\t') rootmycomp python Needleman-Wunsch.py Traceback (most recent call last): File 'Needleman-Wunsch.py', line 92, in (alignedSeq1, alignedSeq2) computeFMatrix (seq1, seq2, -6) File 'Needleman-Wunsch.py', line 34, in.When reading, it is read like this: data = np.loadtxt('data.txt', delimiter=',') Due to the header, if you tried to import it as-is using np.loadtxt (), Python would throw you a ValueError and tell you that it could not convert string to float. numpy.loadtxt 'could not convert string to float'. 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. This error occurred in order to import the data file I originally saved while drawing.
