很抱歉，我之前的回答中有一个错误。我忘记提到你需要先解压缩下载的模型文件。请按照以下步骤进行修改：

1. 下载DeepLabv3+模型权重文件并解压缩：

import tarfile
import urllib.request

# 下载DeepLabv3+模型权重文件
model_url = "http://download.tensorflow.org/models/deeplabv3_mnv2_pascal_train_aug_2018_01_29.tar.gz"
tar_filename = "deeplabv3_mnv2_pascal_train_aug.tar.gz"
urllib.request.urlretrieve(model_url, tar_filename)

# 解压缩
with tarfile.open(tar_filename, "r:gz") as tar:
    tar.extractall()
model_filename = "deeplabv3_mnv2_pascal_train_aug/frozen_inference_graph.pb"

2. 继续后面的代码，进行图像分割。

这样应该可以解决文件不存在的错误。非常抱歉给你带来了困扰。如果还有其他问题，请随时告诉我。
