ubuntu安装FSL 1.下载fslinstaller.py 官网下载地址：https://fsl.fmrib.ox.ac.uk/fsldownloads_registration 或者去我的百度网盘取：链接：https://pan.baidu.com/s/1d5eHm48oamFdYdKm84nifw 提取码：6ff9 2.将base环境改成python2.0版本本来想在服务器安装，服务器没有sudo权限，网上很多教程都装不了，于是就自己安装虚拟机再装了一个ubuntu，然后安装了python2环境，再开始装fsl，fsl 阅读详情

我没辙了，不要怪我问得模糊，这问题实在太奇怪了，代码都一样，我认为没有半点问题。TextOutA和TextOutW都试过了，挂上没反应。
