English

matplotlib was configured to use TkAgg but the environment has no Tk installation or is running headless without DISPLAY.

解决方案

  1. 95% 成功率 
    export MPLBACKEND=Agg
python your_script.py
  2. 82% 成功率 
    sudo apt-get install -y python3-tk tk-dev
# then run under a real X session or Xvfb:
xvfb-run -a python your_script.py

无效尝试

常见但无效的做法:

  1. 95% 失败

    There is no such PyPI package; tkinter ships with the Python interpreter and needs the OS tk-dev package.

  2. 90% 失败

    Reinforces the broken backend choice and fails again at import.
