When converting to a numpy array, how can eliminate the single quotation marks? (python3)-CodePudding

enter image description here

i want this

array([[2600, 11749, 9], [976, 16, 2, ...],...)

But I don't know why single quotes are printed. What should I do?

CodePudding user response：

It seems that numpy arrays of different lengths have been entered into the pandas series.

try this

X_train.values

list(map(np.array, x_train))

CodePudding user response：

It looks like each row in X_train is a string rather than a list, so I think you need to convert those strings to lists. I think this should do it:

X_train = pd.Series([[int(x) for x in string.strip('[]').split(',')] for string in X_train.tolist()])
