**错误1：**UserWarning: nn.functional.sigmoid is deprecated. Use torch.sigmoid instead.
解决方法：找到nn.functional.sigmoid，将其替换为torch.sigmoid。

错误2. Target is multiclass but average=‘binary’. Please choose another average setting
解决方法：加入average=‘micro’

precision = precision_score(Y, np.round(predicted), *average='micro'*)
recall = recall_score(Y, np.round(predicted), *average='micro'*)

**错误3.**RuntimeWarning: invalid value encountered in double_scalars
问题：可能是分母部分出现了0. 加循环，若分母为0，则该项为0.0.
解决：

precision = precision_score(Y, np.round(predicted), average='micro')
recall = recall_score(Y, np.round(predicted), average='micro')
if precision ==0 or recall== 0:
         f1score = 0.0
else:
         f1score = 2*precision*recall/ (precision+recall)

return f1score
