关于scGPT代码finetune_integrate.py文件运行报错

代码在命令行运行正常，在pycharm中报错

pycharm中导包报红线，在命令行执行正常，同样也适用以下解决办法

报错，说在环境中找不到R_HOME

ValueError: r_home is None. Try python -m rpy2.situation

于是，运行Try python -m rpy2.situation得到

从上面可以发现，在Anaconda中创建的虚拟环境里有R_HOME，地址为“D:\Anaconda\envs\BayeAndR\lib\R”，但关机后自动加载的是系统中的R，而我系统中并没有安装R

之前查询过很多方法都说把Anaconda中的R_HOME加入系统环境变量，仍然无法解决问题（不知道为什么），重装环境也能解决问题，但是太费事了

今天发现，直接在Pycharm中要运行的文件中添加环境变量R_HOME就能完美解决问题。
