打包yolov5的detect.py文件遇到问题。我的detect.py里面添加了读取txt文本和写入坐标的功能，运行正常，但是采用pyinstaller打包exe之后，运行会报错。说找不到txt文件。

我的的detect.py代码如下：
# 该段代码是输出识别的种类和坐标
object_name = names[int(cls)]
p1, p2 = (int(xyxy[0]), int(xyxy[1])), (int(xyxy[2]), int(xyxy[3]))
print('object_names is :', object_name, "Upper_left_coordinates：(" + str(p1[0]) + "," + str(
p1[1]) + ")，Lower_right_coordinates(" + str(p2[0])
+ "," + str(p2[1]) + ")")
# 将坐标写进txt文本中
halcon = open('Coordinates.txt', mode='a')
halcon.writelines(str(p1[0]) + "," + str(p1[1]) + "," + str(p2[0]) + "," + str(p2[1]) + ",")
halcon.close()
采用pyinstaller打包。采用配置文件打包.spec,配置文件如下：
# -*- mode: python ; coding: utf-8 -*-
block_cipher = None
a = Analysis(
['detect.py'],
pathex=[],

非python的用户文件pyinstaller 是不会打包的，需要添加，比如你的数据文件，外部系统配置文件等等，需要你放到程序中指定的位置上才行，所以，建议不要采用绝对路径的方式进行文件读写操作
--add-data 参数将这些文件包含进来，否则在运行时可能会出现找不到文件的错误。例如，如果您的 detect.py 中使用了一个名为 data.txt 的文件，那么您可以这样打包：
pyinstaller detect.py --add-data "data.txt;."
open('data.txt') 来打开文件，那么在打包后的程序中也应该使用 open('data.txt') 来访问文件。此外，如果您的 detect.py 中使用了绝对路径来访问文件，那么在打包后的程序中这些路径可能会发生变化，因此您需要注意修改这些路径。
解决 pyinstaller 打包时，包含的数据找不到
如有帮助，望采纳
https://blog.csdn.net/u012917013/article/details/125860885
a = Analysis( ... )
里面添加
a.datas += [
("/absolute/path/to/some.txt","txt_files/some.txt","DATA"),
("/absolute/path/to/some2.txt","txt_files/some2.txt","DATA"),
("/absolute/path/to/some3.txt","txt_files/some3.txt","DATA"),
]
然后代码里面这获取文件
def resource_path(relative_path):
""" Get absolute path to resource, works for dev and for PyInstaller """
try:
# PyInstaller creates a temp folder and stores path in _MEIPASS
base_path = sys._MEIPASS
except Exception:
base_path = os.environ.get("_MEIPASS2",os.path.abspath("."))
return os.path.join(base_path, relative_path)
...
txt_data = open(resource_path("txt_files/some.txt")).read()
