如何用U盘安装 debian linux 系统
- 博客分类:
- 指导篇
首先下载Win32DiskImager-0.9.5-install、debian-8.4.0-amd64-DVD-1.iso 系统,iso不要放在u盘中,放在本地pC中 不然 用DiskImager,不成功。
其他的按照 https://jingyan.baidu.com/article/4b07be3cb16a4e48b280f361.html

Use case:

RNN 的shape [B, T, ...]其中B batch size ,T每次输入的长度,如句子单词的长度,剩下的维度取决于数据。
如果说single batch 里面所有的句子长度不同,但是RNN要求必须一样,所以必须填充,因此需要padding 他们,一般填充0.
如果仅有几个句子长度是1000,平均长度是20,如果全部填充到1000,那浪费的很多。因此需要batch padding。
如果设定batches size 为32,那么主要保持这次batch一样就可以了,下次patch可以和上次不一样,这样,只有个别的1ooo需要填充,节约了空间
可以使用 tf.train ...
