今天突然发现，Pycharm里原来也可以集成Jupyter！

然后，本人便兴冲冲地去实现了Jupyter+Pycharm+anaconda的环境部署。。。

然而。。。事情并没有想象的那么简单。。

在成功地安装完了环境之后，本人十分愉（zi）快（xin）地点击了运行cell，以下是报错：

接下来 进入报错的那个文件 D:\Program Files\anaconda\envs\torchPro\lib\subprocess.py

hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
                                         # no special security
                                         None, None,
                                         int(not close_fds),
                                         creationflags,
                                         env,
                                         os.fspath(cwd) if cwd is not None else None,
                                         startupinfo)

我确确实实地带着这串代码去网上转了好几圈，，结果还是找不出问题所在。o(╥﹏╥)o

不过最后当我切回Pycharm运行界面时，我发现

我之前选的是上面那个，也没搞太清楚是怎么回事，但是选了Python 3 以后就解决了。。
