loss出现Nan,通常来说有两种可能的原因。一是训练数据存在脏数据,二是出现梯度爆炸或者梯度损失。 脏数据会导致非法计算的出现。比如 ,或者模型输出的类别与实际的类别数不匹配等。如果训练数据的顺序是固定的,模型总是在固定的轮数出现loss变为Nan就要高度怀疑是数据...
我按照这个教程进行的纯中文的fine-tune,也就是各个命令行中输入“C”的,输入一段30分钟的非常标准的中文长音频。由于GPU配置不高,只有将配置文件configs/modified_finetune_speaker.json中的batch_size设置为2的时候才能开始训练,不然都会报OOM。但是训练的结果令我很吃惊,日志中出现了很多Nan的数据,不知道是为什么,...

而_kl_div_non_log_target有些许不同,因为target的数值范围不确定,当为负数的时候,log运算时不合法的。因此Pytorch初始化了一个全0数组,然后在最后的loss计算中,在target小于0的地方填0,避免nan数值出现 下面是对应的numpy实现代码 defnp_kldivloss(input, target, lo...
