[英]f1_score() takes 2 positional arguments but 3 positional arguments (and 1 keyword-only argument) were given
from sklearn.metrics import f1_score
F1_score = f1_score(lab2d, pred2d, [0, 1, 2, 3], average=None)
print("Validation Dice Coefficient.... ")
print("Background:", F1_score[0])
print("CSF:", F1_score[1])
print("GM:", F1_score[2])
print("WM:", F1_score[3])
```
这是错误
f1_score() takes 2 positional arguments but 3 positional arguments (and 1 keyword-only argument) were given
我尝试以不同的方式传递 arguments 但仍然出现相同的错误
正如 1.2.0 版的文档所述,您需要像这样调用 function
from sklearn.metrics import f1_score
y_true = [0, 1, 2, 0, 1, 2]
y_pred = [0, 2, 1, 0, 0, 1]
f1_score(y_true, y_pred, average='macro')
请注意,它接受 3 arguments: y_true
、 y_pred
和关键字参数average
。 您正试图在[0, 1, 2, 3]
中添加一个额外的参数。 它或前两个 arguments ( lab2d
或pred2d
)之一应该被删除。
