python列表切片操作教学 113.PythonPaddleHub图像分类项目打包一例

写过关于图像语义检索的文章，详情可以参看：90.人工智能——基于ImageAI实现图像语义的检索。ImageAI是用的是tensorflow框架，后面改用飞桨框架，用PaddleHub来实现建立图像索引。主要是使用训练好的图像分类模型。

关于飞桨框架打包篇可以参看：111.Python——基于pipenv打包PaddlePaddle的GUI项目。

本文在上面的基础上，增加了一个PaddleHub，PaddleHub即开即用。

记录一下这个PaddleHub PyQt5项目打包的问题。打包总是会遇到很多问题，因为折腾了很久，所以在这里记录一下。

版本： paddlehub 2.2.0 paddlenlp 2.3.4 paddlepaddle 2.3.1

错误信息如下：

根据错误提示，网上查找了一通，但没有解决实际问题。分析错误信息中的提示，发现问题是由paddlenlp引起的，但本项目中没有使用到paddlenlp，所以临时解决思路：

1、修改文件：Lib\site-packages\paddlehub\datasets\ __init__.py，屏蔽以下关于paddlenlp的引用三处。

from paddlehub.datasets.canvas import Canvas #from paddlehub.datasets.chnsenticorp import ChnSentiCorp from paddlehub.datasets.esc50 import ESC50 from paddlehub.datasets.flowers import Flowers from paddlehub.datasets.minicoco import MiniCOCO #from paddlehub.datasets.msra_ner import MSRA_NER #from paddlehub.datasets.lcqmc import LCQMC from paddlehub.datasets.base_seg_dataset import SegDataset from paddlehub.datasets.opticdiscseg import OpticDiscSeg

2、打包的时候排除:paddlenlp

打开.spec文件，设置excludes=['paddlenlp']

或者直接使用排除模块参数： --exclude-module padelenlp

最后顺利打包成功，生成的exe文件约200MB,基本是可以接受的，虽然还是有些大。脱离环境的运行效果。

说明：问题的根源还是没有找到，如果能有解决该问题的方法，希望能分享出来。
