i was running this code :

data = pd.DataFrame(index=np.arange(0, total_images), columns=["patient_id", "path", "target"])

k = 0

for n in range(len(folder)):

    patient_id = folder[n]

    patient_path = base_path +"/"+ patient_id 

    for c in [0,1]:

        class_path = patient_path + "/" + str(c) + "/"

        subfiles = listdir(class_path)

        for m in range(len(subfiles)):

            image_path = subfiles[m]

            data.iloc[k]["path"] = class_path + "/" +image_path

            data.iloc[k]["target"] = c

            data.iloc[k]["patient_id"] = patient_id

            k += 1  

data.head(100)

and am getting this error
