ValueError: could not convert string to float: '"840343879668908032"'

this is the code i tried to execute

X = train_attr.to_numpy()
Y = train_label.to_numpy()

logreg = LogisticRegression().fit(train_X, train_Y)

CodePudding user response：

you have additional quotation marks in the string that you are trying to convert to float.

CodePudding user response：

The string you are trying to convert is this

"840343879668908032"

but it should be this

840343879668908032

Python is taking double quotes as a part of the string, This may be because you would have used quotes multiple time like this

sample_str = '"840343879668908032"'
or
sample_str2 = '"1321351"'

so you should remove the additional quotes and for example do

sample_str = '840343879668908032'
