bootstrap项目pyinstaller打包包含torch,torchvision,pyzbar不成功解决⽅案1 pyinstaller 对与torchvision 只能⽀持0.3.0以下，好像是这样，不然会出问题，
我⽤的版本是torch1.5.1 cpu  和torchvision0.6.1cpu，打包出现⽐如这样的错误

尝试了很多办法，都不⾏。我想不如直接把torch和torchvision当成⾃⼰项⽬的⼀部分算了。
然后我直接把torch和torchvision这两个包从安装路径粘出来放到项⽬根⽬录下，作为项⽬⾃⼰的导⼊包。
然后从开发环境中卸载者两个包，既pip uninstall torch, 和pip uninstall torchvision。
卸载完之后，我把项⽬中的torchvision重命名为torchvision1。如下图，然后在项⽬中需要导⼊torchvison的地⽅，全部改成torchvision1，因为要导⼊项⽬中的torchvision1，还有就是为了和环境中的torchvision作区分嘛。这个改名字是为了保险免得和环境中的搞混了。
然后⽤pyinstaller打包，pyinstaller -D -c xxx.py。    -D是打包成⽂件夹，-c是运⾏时有控制台的输出信息。具体⽤法⾃⼰百度。
完成后，可能有些包不会打进去，需要⾃⼰把这些包从安装⽬录中粘过去。
⽐如打包后，torvhvision1这个包不会⾃⼰添加进去，⼿动放过去，还有其他的需要的包。运⾏的时候看看，粘过去就好。
差不多就完成了。
运⾏的时候最好最好在⽣成的打包⽂件夹下运⾏，特别cmd运⾏的时候，⼀定要先打包的⽂件夹。不然有可能出问题。
还有就时如果⽤到cv2 还有numpy，注意这两个包的版本应该匹配。不然会报错
⽐如
ImportError: ultiarray failed to import
解决⽅案：
解决思路，改变控制台的编码格式为utf-8
解决⽅法01，在控制台中输⼊ chcp 65001，然后再使⽤pyinstaller -D  xxx.py 打包成功。  这个试⼀下，可能有⽤。
第⼆个是我的解决⽅案。
这是因为cv2要求的numpy版本与你装的numpy版本不⼀样，导致冲突；⽹上很多说升级numpy，但你把numpy升的再新，cv2要求的版本却是旧的好吗？
所以将两者都重新安装为适配版本就⾏，如下：
1pip install opencv-python==3.4.2.17numpy==1.14.5
或者可以试试只将numpy版本降低
1pip install numpy==1.14.5
。
差不多就这样。
结果如图
运⾏结果
