[Mark]|[Mark] pyinstaller打包含有transformers依赖程序时出现PackageNotFoundError [Mark]pyinstaller打包含有transfor

背景
最近有一个项目在使用到了transformers这个包，因为加密需要所以使用了pyinstaller对程序打了包，程序执行的时候发现了以下报错：

Traceback (most recent call last): File "transformers/utils/versions.py", line 105, in require_version File "importlib_metadata/__init__.py", line 994, in version File "importlib_metadata/__init__.py", line 967, in distribution File "importlib_metadata/__init__.py", line 561, in from_nameimportlib_metadata.PackageNotFoundError: No package metadata was found for XXXDuring handling of the above exception, another exception occurred:Traceback (most recent call last): File "service/server.py", line 6, in File "PyInstaller/loader/pyimod03_importers.py", line 546, in exec_module File "model/tagging/infer_handler.py", line 1, in File "PyInstaller/loader/pyimod03_importers.py", line 546, in exec_module File "transformers/__init__.py", line 43, in File "PyInstaller/loader/pyimod03_importers.py", line 546, in exec_module File "transformers/dependency_versions_check.py", line 41, in File "transformers/utils/versions.py", line 120, in require_version_core File "transformers/utils/versions.py", line 108, in require_versionimportlib_metadata.PackageNotFoundError: No package metadata was found for The 'XXX' distribution was not found and is required by this application. Try: pip install transformers -U or pip install -e '.[dev]' if you're working with git master

解决方法

For every package listed in pkgs_to_check_at_runtime (except python), you will need to collect metadata, by using copy_metadata(name) in your spec file.
For quick prototyping, you can also use --copy-metadata command-line switch (i.e., add --copy-metadata tqdm --copy-metadata regex --copy-metadata sacremoses ... to your PyInstaller command-line).
And I seem to recall that at least one of those packages also requires a --collect-data (or collect_data_files() in spec).

原帖重点的部分我进行了加粗，参考原帖的思路为采用修改 xxx.spec (pyinstall生成的打包文件)解决这个问题

找到需要使用copy_metadata方法告知pyinstaller需要添加的数据文件
在你程序对应的python环境中查看需要拷贝的数据文件的包有哪些

from transformers.dependency_versions_check import pkgs_to_check_at_runtime print(pkgs_to_check_at_runtime)

out:

['python', 'tqdm', 'regex', 'sacremoses', 'requests', 'packaging', 'filelock', 'numpy', 'tokenizers', 'importlib_metadata']
修改. spec文件

...from PyInstaller.utils.hooks import collect_data_files, copy_metadata...# tqdm issue for https://github.com/pyinstaller/pyinstaller/discussions/6033 datas = copy_metadata('tqdm') datas += copy_metadata('torch') datas += copy_metadata('regex') datas += copy_metadata('sacremoses') datas += copy_metadata('requests') datas += copy_metadata('packaging') datas += copy_metadata('filelock') datas += copy_metadata('numpy') datas += copy_metadata('tokenizers') datas += copy_metadata('importlib_metadata')...a = Analysis(... datas=datas, ...) ...
