错误:(-215)ssize.width> 0&& ssize.height>函数调整大小为0 [英] error: (-215) ssize.width > 0 && ssize.height > 0 in function resize

问题描述

我正在构建图像处理分类器，除此行外，整个代码都正确-

I am building image processing classifier the whole code in right except this line -

input_img_resize=cv2.resize(input_img,(128,128))

此行给我一个错误

('error: /io/opencv/modules/imgproc/src/imgwarp.cpp:3483: error: (-215) ssize.width > 0 && ssize.height > 0 in function resize')

我的代码-

PATH = os.getcwd()
# Define data path
data_path = PATH + '/data'
data_dir_list = os.listdir(data_path)

img_rows=128
img_cols=128
num_channel=3
num_epoch=30

num_classes = 67

img_data_list=[]

for dataset in data_dir_list:
    img_list=os.listdir(data_path+'/'+ dataset)
    print ('Loaded the images of dataset-'+'{}\n'.format(dataset))
    for img in img_list:
        input_img=cv2.imread(data_path + '/'+ dataset + '/'+ img )

        input_img_resize=cv2.resize(input_img,(128,128))
        img_data_list.append(input_img_resize)

推荐答案

好吧，显然这行 input_img=cv2.imread(data_path + '/'+ dataset + '/'+ img ) 返回一个空数组.

Well, obviously this line input_img=cv2.imread(data_path + '/'+ dataset + '/'+ img ) return a empty array.

读取之前，应先检查图像是否存在.并且请停止使用字符串组合来连接文件路径，使用python os.path.join是更好的选择.

You should check whether image is exist first before reading. And please stop using string combination to join file path, use python os.path.join is better choice.

image_path = os.path.join(data_path, dataset, img)
if os.path.exist():
    # Do stuff
