I also meet this problem "the img_buffer get none",the sub-function "imread" in dataset.py,the img_buffer get key but whit None

Just ignore lmdb. Replace imread function of dataset.py with

    def imread(self, path):
        # key = hashlib.md5(path.encode()).digest()
        # img_buffer = self.txn.get(key)
        # img_buffer = np.frombuffer(img_buffer, np.uint8)
        # img = cv2.imdecode(img_buffer, cv2.IMREAD_COLOR)
        img = cv2.imread(path, cv2.IMREAD_COLOR)
        return img
