@mind3x 大概是把实现造成的特性写在文档里让人 exploit 让我觉得奇葩.
@mind3x 但是我还是想说,我面的人如果这样用 reduce 我肯定给 N, 我不 care 一个具体语言里它怎么玩他的 API, 但你解题必须要体现出你的 cs 基本功, 非对易算符用了 reduce 结果是 inconsistent 的.
@mind3x 我不知道,我玩惯了 cudnn 的 reduce,python 这种奇葩实现我不想说什么,
没有人说 reduce 的语义不保证执行顺序吗,楼主根本不懂 reduce
分享一个我平时用的
```
from PIL import Image
import pyheif
import numpy as np


def decode_heic(image_filepath):
"""Decode image into numpy array, in HWC RGB format
Args:
image_filepath: str
Returns:
im_rgb: numpy.ndarray, (H, W, C), RGB, uint8
"""
i = pyheif.read_heif(open(image_filepath, 'rb'))
im_rgb = np.array(Image.frombytes(mode=i.mode, size=i.size, data=i.data))
return im_rgb

def decode_heic_to_im(image_filepath):
"""Decode image into numpy array, in HWC RGB format
Args:
image_filepath: str
Returns:
im_rgb: numpy.ndarray, (H, W, C), RGB, uint8
"""
i = pyheif.read_heif(open(image_filepath, 'rb'))
im = Image.frombytes(mode=i.mode, size=i.size, data=i.data)
return im
```
如果要保存为.png/.jpeg:
`decode_heic_to_im('somefile.heic').save('somefile.png')` 就可以了

PT 这种盗版行为怎么没见一个喷的。
看论文还是得纸质的比较爽,除非买十个 ipad 在桌上一字铺开
如果一个 nn graph 在从一个 node 到另一个 node 时的 path 有很多个而且 noneterministic,那么很可能就类似于一个模糊的运算。 同理, 如果一个 graph 中有大量 non derministic recurrent/recursive node, 可能就类似于模糊记忆。 一句话总结:上述的 graph 现在的算力完全 train 不动
宏是 meta-peogrammung 神器啊
