Ubuntu系统FastAI项目报错：libtinfo.so.5无法打开共享对象文件

运行基于Ubuntu的系统中的FastAI Python项目时，出现以下错误：

Traceback (most recent call last):
  File "/home/me/PycharmProjects/project/model/predict.py", line 6, in <module>
    from fastai.vision.all import *

ImportError: libtinfo.so.5: cannot open shared object file: No such file or directory

解决步骤 #

方法一：直接安装缺失库 #

通过系统包管理器安装libtinfo5：

sudo apt update
sudo apt install libtinfo5

方法二：创建软链接（适用于已安装高版本libtinfo的情况） #

如果Ubuntu版本为20.04+，系统通常自带libtinfo.so.6，可通过软链接兼容低版本依赖：

sudo ln -s /lib/x86_64-linux-gnu/libtinfo.so.6 /lib/x86_64-linux-gnu/libtinfo.so.5

验证修复 #

完成上述操作后，重新运行FastAI项目，确认错误已消除。
