Error decoding JSON from C:\Users\admin\AppData\Roaming\Ultralytics\persistent_cache.json starting with an empty dictionary

当我将我的yolo文件打包成exe文件的时候：我已经在spec文件中添加：
When I packaged my yolo procedure into an exe file: I had added to the spec file:
datas=collect_data_files('ultralytics'),
但是打包成exe之后发送给用户，在用户机上（一台未安装python和ultralytics的机器上）点击运行.exe文件会出现：
However, after packaging it into exe and sending it to the user, clicking Run.exe on the user PC (a PC without python and ultralytics installed) will result in:
Error decoding JSON from C:\Users\admin\AppData\Roaming\Ultralytics\persistent_cache.json starting with an empty dictionary
这个文件当中的内容应该是：
this file's content should be is:

{
  "cpu_info": "AMD Ryzen 7 6800H with Radeon Graphics"
}

明显的，这是一个动态生成的内容，我不能粗暴的直接打包这个文件，请问我应该怎么让我的exe文件可以在一台没有安装python的电脑上运行
Obviously, this is a dynamically generated content, I can't roughly package this file directly, how can I make my exe file run on a computer without python and ultralytics installed?

👋 Hello @Huang-Ifei, thank you for bringing this up and for your interest in Ultralytics 🚀!

It looks like you're encountering an issue while packaging your YOLO project into an .exe file, specifically related to the dynamically generated persistent_cache.json. Here's how you can proceed to address this:

Initial Recommendations

If this is a 🐛 Bug Report, providing a minimum reproducible example (MRE) will significantly help us understand and debug the issue. For example:

1. The complete .spec file you've used for packaging.
2. Any modifications you've made to your YOLO code or dependencies during the packaging process.
3. Steps to reproduce the issue on a clean environment.

For compatibility, ensure you're using the latest version of the ultralytics package. You can upgrade via pip:

pip install -U ultralytics

Key Debugging Steps

• Double-check your packaging process, including the inclusion of data files and dynamically generated runtime files like persistent_cache.json.
• Consider specifying default paths or creating a mechanism to generate these transient files dynamically during runtime if they are missing.

@Huang-Ifei for PyInstaller deployments with Ultralytics YOLO, we recommend implementing a first-run initialization check in your code to handle missing cache files. Add this before your main logic:

from pathlib import Path
cache_path = Path.home() / 'AppData/Roaming/Ultralytics/persistent_cache.json'
if not cache_path.exists():
    cache_path.parent.mkdir(parents=True, exist_ok=True)
    cache_path.write_text('{}')  # Initialize empty JSON

This creates the necessary file structure while maintaining proper Ultralytics functionality. For deployment best practices, see the PyInstaller integration guide in our documentation.

Thank you very much. This has solved a major problem for me.
