在Windows 7 64bit上运行ipyhton笔记本并启动带有python 2内核的笔记本时出现错误:

WindowsError: [Error 2] The system cannot find the file specified
我进一步调查过,我在launcher.py文件中的proc = Popen(cmd, **kwargs)
之前添加了以下打印行
print cmd
print kwargs
现在我看到使用cmd =
调用proc = Popen(cmd, **kwargs)
['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
中C:\\Users\\USER1\\Anaconda2_32bit\\python.exe
但在
C:\\Users\\USER1\\Anaconda2\\python.exe
但是我检查了计算机/高级系统设置/高级/环境变量中的路径,并且从未在那里指定\\Anaconda2_32bit\\
。
因此我怀疑在其他地方指定了错误路径。这可能在哪里,我该如何解决?
此外,我之前在\\Anaconda2_32bit\\
安装了Anaconda,但我已将其卸载。
答案 0 :(得分:8)
ipython在特殊配置文件中注册了内核 我已经运行了命令:
ipython kernelspec list
输出是:
Available kernels:
python2 C:\ProgramData\jupyter\kernels\python2
我查看了C:\ProgramData\jupyter\kernels\python2\kernel.json
文件,并且为python2设置了错误的路径。我已经修好了路径,现在就可以了。
