PixelLib Pixel Lib Value Error

HI, everyone

SO i am trying to do instance segmentation with PIxel lib ,but get the following Value Error

My Code:

import pixellib
from pixellib.tune_bg import alter_bg
from pixellib.instance import instance_segmentation  
from matplotlib import pyplot as plt
from PIL import Image

segmentation_model = instance_segmentation()

segmentation_model.load_model("./mask_rcnn_balloon.h5")

target_classes = segmentation_model.select_target_classes(people == "True")

My Error:

ValueError                                Traceback (most recent call last)

ValueError: 

Layer #389 (named "mrcnn_bbox_fc"), weight <tf.Variable 'mrcnn_bbox_fc/kernel:0' shape=(1024, 324) dtype=float32> has shape (1024, 324), but the saved weight has shape (1024, 8).

There is no option for excludng "mrcnn_bbox_fc". Please Help :(

EDIT: OK, so it WORKS with 2.0 but not 2.1 baloon.h5 Model (Why is that ? )
