如何从 scipy.misc.imresize 转换为 imageio

Question

嗨，我是运行一个稍微贵一点的 aws... 并试图将旧的 scipy.imread 解决到新的 imagio.read 标准。

在这个文件中 https://github.com/ml5js/training-styletransfer/blob/master/src/utils.py

    import scipy.misc, numpy as np, os, sys

def save_img(out_path, img):
    img = np.clip(img, 0, 255).astype(np.uint8)
    scipy.misc.imsave(out_path, img)

def scale_img(style_path, style_scale):
    scale = float(style_scale)
    o0, o1, o2 = scipy.misc.imread(style_path, mode='RGB').shape
    scale = float(style_scale)
    new_shape = (int(o0 * scale), int(o1 * scale), o2)
    style_target = _get_img(style_path, img_size=new_shape)
    return style_target

def get_img(src, img_size=False):
   img = scipy.misc.imread(src, mode='RGB') # misc.imresize(, (256, 256, 3))
   if not (len(img.shape) == 3 and img.shape[2] == 3):
       img = np.dstack((img,img,img))
   if img_size != False:
       img = scipy.misc.imresize(img, img_size)
   return img

def exists(p, msg):
    assert os.path.exists(p), msg

def list_files(in_path):
    files = []
    for (dirpath, dirnames, filenames) in os.walk(in_path):
        files.extend(filenames)
        break

    return files

有 imresize 我如何将其转换为新标准。

（还有几个错误出现，好像模式应该是 pilmode？）

次要问题有没有简单的方法来转换这些文件？

项目代码有很多问题运行。

但这是一个我似乎无法修复的问题

imresize 不再是 scipy 的一部分。您可以降级到 scipy 即 1.2.1 或安装 scikit-image 并调用 skimage.transform.resize 而不是
