python - 从 Matlab 运行 python 脚本 - 无法加载 matplotlib

Question

所以我需要从 matlab 运行 python 脚本。这个 python 脚本加载 matplotlib，这似乎是一个问题。我已复制电子邮件末尾的错误。

详细信息

1. 平台 - Linux
2. 当我从终端执行这个 python 脚本时，它运行良好。
3. 当我从不使用 matplotlib 的 matlab 执行另一个 python 脚本时，我似乎没有问题。

4. 在 ma​​c 上，我的一个 friend 能够通过将命令修改为

   从 matlab 运行脚本

   syscmd = sprintf('export DYLD_LIBRARY_PATH=""; python sim/loglike.py %s %s', 'sim/queryIn_0515-161222', 'sim/temp.txt'), system(syscmd)

请给我任何关于这方面的指示。我无法通过 Google 找到解决方案

最好的，

>> syscmd = sprintf('python sim/loglike.py %s %s', 'sim/queryIn_0515-161222', 'sim/temp.txt'), system(syscmd)

syscmd =

python sim/loglike.py sim/queryIn_0515-161222 sim/temp.txt

Matlab 不使用系统库(它设置 LD_LIBRARY_PATH 变量)。试试这个:

system('LD_LIBRARY_PATH='''' python my_script.py')
