I also meet the problem, have you issued?

I guess that it may be caused by the change of the filefolder path.

Plz note that when you create the lmdb you need to send the path md5 as the key. So if you change the ".lmdb" path, you need to change the generated key for further query. (Or you will get nothing for the false key you get.)

Also note that :

    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)
        return img

If you change the .lmdb filefolder path, you should change the path to the original path when you use a different filedir. ( Before key = hashlib.md5(path.encode()).digest())
