在Windows 7 64位系统上运行ipython笔记本并使用Python 2内核启动笔记本时,出现错误:
这是一个问题,因为我的python.exe不在这里。

我进一步调查了这个问题,并在launcher.py文件中的proc = Popen(cmd, **kwargs)
之前添加了以下打印行:
print cmd
print kwargs
现在我看到proc = Popen(cmd, **kwargs)
是使用cmd=调用的
['C:\\Users\\USER1\\Anaconda2_32bit\\python.exe', '-m', 'ipykernel', '-f', '
C:\\Users\\USER1\\AppData\\Roaming\\jupyter\\runtime\\kernel-a3f46334-4491-4
fef-aeb1-6772b8392954.json']
这是一个问题,因为我的python.exe不在这里。
C:\\Users\\USER1\\Anaconda2_32bit\\python.exe
but in
C:\\Users\\USER1\\Anaconda2\\python.exe
然而,我已经在“计算机/高级系统设置/高级/环境变量”中检查了路径,从未指定\\Anaconda2_32bit\\
。
因此,我怀疑虚假路径在其他地方被指定。它可能在哪里?我该如何修复它?
另外,我以前安装过Anaconda在\\Anaconda2_32bit\\
,但我已经卸载了它。
ipython
命令的弃用,现在建议使用jupyter kernelspec list
进行操作。 - whoopscheckmate
