在QGIS插件中安装geopandas遇numpy版本兼容及重载错误

操作流程 #

• 创建虚拟环境（venv）
• 安装geopandas
• 将虚拟环境的site-packages目录添加至Python路径
• 导入geopandas

问题详情 #

执行上述步骤后触发版本兼容报错：当前numpy版本为1.21.5，而安装的pandas版本要求numpy≥1.22.4。尝试通过importlib.reload()重载numpy以调用虚拟环境中的高版本时，又出现无法从numpy._globals导入_CopyMode的错误，怀疑QGIS的qgis/utils.py中的_import方法干扰了正常导入逻辑，目前无解决思路。

相关代码与报错信息 #

原安装代码 #

# sys.executable - QGIS Python解释器路径
# venv_path - 虚拟环境路径
# venv_pip_path - 虚拟环境中pip的路径
# venv_site_packages_path - 虚拟环境site-packages路径

import sys
import subprocess
from importlib import import_module

subprocess.run([sys.executable, "-m", "venv", "--copies", venv_path], check=True)
subprocess.run([venv_pip_path, "install", "geopandas"], check=True)
sys.path.insert(0, venv_site_packages_path)
import_module("geopandas")

版本兼容报错 #

ImportError: this version of pandas is incompatible with numpy < 1.22.4
your numpy version is 1.21.5.
Please upgrade numpy to >= 1.22.4 to use this pandas version

重载numpy代码 #

from sys import modules
import importlib

importlib.reload(modules['numpy'])

重载报错 #

File "/usr/lib/python3.10/importlib/__init__.py", line 169, in reload
    _bootstrap._exec(spec, module)
  File "<frozen importlib._bootstrap>", line 619, in _exec

    from ._globals import _NoValue, _CopyMode
ImportError: cannot import name '_CopyMode' from 'numpy._globals' (/usr/lib/python3/dist-packages/numpy/_globals.py)

怀疑的干扰代码 #

File "/usr/lib/python3/dist-packages/qgis/utils.py", line 923, in _import
    mod = _builtin_import(name, globals, locals, fromlist, level)
