我遇到问题

AttributeError：“过滤器”对象没有属性“排序”

下面是整个错误消息：

Using TensorFlow backend.
Traceback (most recent call last):

def data_to_array(img_rows, img_cols):
    clahe = cv2.createCLAHE(clipLimit=0.05, tileGridSize=(int(img_rows/8),int(img_cols/8)) )

    fileList =  os.listdir('TrainingData/')
    fileList = filter(lambda x: '.mhd' in x, fileList)
    fileList.sort()

Answer 1

在python 3中，filter返回可迭代。并且您在iterable上调用sort方法，从而得到一个错误。要么将迭代包装在列表中

fileList = list(filter(lambda x: '.mhd' in x, fileList))

或代替fileList.sort()以有序方法传递迭代器

fileList= sorted(fileList)

Python 3 doc for filter

Answer 2

您正在使用Python3。Filter返回一个可迭代的filter对象，但没有sort方法。将过滤器对象包装在list中。

fileList = list(filter(lambda x: '.mhd' in x, fileList))

AttributeError：Python“过滤器”对象没有属性“ sort”
