请告诉我为什么会出现这个错误？

我应该如何更正它？

如评论中讨论的，reorder 参数已在版本 0.20 中弃用，并在 0.22 中移除。
def roc_aupr_score(y_true, y_score, average="macro"):
def _binary_roc_aupr_score(y_true, y_score):
precision, recall, pr_thresholds = precision_recall_curve(y_true, y_score)
return auc(recall, precision)
应该按预期工作。如果不行，你可以像这样对 `precision` 和 `recall` 进行排序：
```python
precision, recall, pr_thresholds = precision_recall_curve(y_true, y_score)
new_order = np.lexsort([recall, precision])
recall = recall[new_order]
precision = precision[new_order]
print(recall, precision)
return auc(recall, precision)
英文:
As discussed in the comments, reorder parameter has been deprecated in version 0.20 and removed in 0.22
def roc_aupr_score(y_true, y_score, average="macro"):
def _binary_roc_aupr_score(y_true, y_score):
precision, recall, pr_thresholds = precision_recall_curve(y_true, y_score)
return auc(recall, precision)
Should work as intented. If not, you can sort precision and recall like this:
precision, recall, pr_thresholds = precision_recall_curve(y_true, y_score)
new_order = np.lexsort([recall, precision])
recall = recall[new_order]
precision = precision[new_order]
print(recall , precision )
return auc(recall, precision)
