我正在尝试将png文件读入在docker中运行的python-flask应用程序中,并收到一条错误消息,内容为
ValueError:找不到在模式“ i”下读取指定文件的格式
我已经使用HTML文件上传了文件,现在我正尝试阅读该文件以进行进一步处理。我看到scipy.misc.imread已被弃用,我正尝试将其替换为imageio.imread
if request.method=='POST':
file = request.files['image']
if not file:
return render_template('index.html', label="No file")
#img = misc.imread(file)
img = imageio.imread(file)

我收到此错误:

最近遇到了完全相同的问题,问题是单个损坏的文件。最好是使用 PIL 之类的东西来检查坏文件。
import os
from os import listdir
from PIL import Image
dir_path = "/path/"
for filename in listdir(dir_path):
if filename.endswith('.jpg'):
try:
img = Image.open(dir_path+"\\"+filename) # open the image file
img.verify() # verify that it is, in fact an image
except (IOError, SyntaxError) as e:
print('Bad file:', filename)
#os.remove(dir_path+"\\"+filename) (Maybe)

不同,但以防万一。我在不同的库(skimage)中有一个相同的错误,解决方案是添加一个额外的“ plugin”参数,如下所示:
image = io.imread(filename,plugin='matplotlib')
