从Python中的不同文件夹中读取文件列表

Question

for root, dirs, files in os.walk(os.getcwd()):
    for dirct in dirs:
    lis_sal_map =[]
    gt = ''
    for name in files:
    
       (base, ext) = os.path.splitext(name) # split base and extension
        if ext in ('.jpg'):          # check the extension
            gt = name
            print("gt old is", gt)
        if ext in ('.png'):
        #full_name = os.path.join(root, name)
            lis_sal_map.append(name)
    print("list sal map", lis_sal_map) 
        
    
print("gt before file", gt)
img_gt = Image.open(gt)
numpydata_in = np.array(img_gt).astype('uint8')
numpydata_out = list_sal_map[0]
nss = nss(numpydata_in, numpydata_out)
print("nss is", nss)

我有18个文件夹，每个文件夹包含10张图像，一个图像作为地面真理，另一些作为预测的图像。我正在尝试编写一个程序，该程序将逐一访问这18个文件夹并比较每个文件夹中的图像。您能帮我解决问题吗？我获得的当前输出如下：

list sal map []
list sal map []
gt befoe file 
Traceback (most recent call last):

fp.seek(0)
AttributeError: 'str' object has no attribute 'seek'

During handling of the above exception, another exception occurred:

Trace back (most recent call last):
File "result_auto.py", line 61, in <module>
img_gt = Image.open(gt)

fp = io.BytesIO(fp.read())
