多分类损失函数label.shape:[batch_size];pred.shape:[batch_size,num_classes]运用tf.keras.losses.sparse_categorical_crossentropy(y_true,y_pred,from_logits=False,axis=-1)–y_true真实值,y_pred预测值–from_logits,我的理解是,如果预测结果经过了softmax(单次预测结果满足和为1)就运用设为`False`,  如果预测结果未经过softmax就设为`True`.pred=tf.c

在日常工作中,钉钉打卡成了我生活中不可或缺的一部分。然而,有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚,我总是得牢记打开钉钉应用,点击"工作台",再找到"考勤打卡"进行签到。有时候因为工作忙碌,会忘记打卡,导致考勤异常,影响当月的工作评价。而且,由于我使用的是苹果手机,有时候系统更新后,钉钉的某些功能会出现异常,使得打卡变得更加麻烦。 另外,我的家人使用的是安卓手机,他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说,每次打卡都是一次挑战。他们总是担心自己会操作失误,导致打卡失败。 为了解决这些烦恼,我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习,我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
