Ipython 笔记本，如何设置正确的内核路径

Question

当运行 ipyhton notebook 在 Windows 7 64bit 上启动笔记本 python 2 内核时，我得到一个错误：

Traceback (most recent call last):
  File "C:\Users\USER1\Anaconda2\lib\site-packages\notebook\base\handlers.py", line 436, in wrapper
    result = yield gen.maybe_future(method(self, *args, **kwargs))
  File "C:\Users\USER1\Anaconda2\lib\site-packages\notebook\services\sessions\handlers.py", line 56, in post
    model = sm.create_session(path=path, kernel_name=kernel_name)
  File "C:\Users\USER1\Anaconda2\lib\site-packages\notebook\services\sessions\sessionmanager.py", line 66, in create_session
    kernel_name=kernel_name)
  File "C:\Users\USER1\Anaconda2\lib\site-packages\notebook\services\kernels\kernelmanager.py", line 84, in start_kernel
    **kwargs)
  File "C:\Users\USER1\Anaconda2\lib\site-packages\jupyter_client\multikernelmanager.py", line 109, in start_kernel
    km.start_kernel(**kwargs)
  File "C:\Users\USER1\Anaconda2\lib\site-packages\jupyter_client\manager.py", line 244, in start_kernel
    **kw)
  File "C:\Users\USER1\Anaconda2\lib\site-packages\jupyter_client\manager.py", line 190, in _launch_kernel
    return launch_kernel(kernel_cmd, **kw)
  File "C:\Users\USER1\Anaconda2\lib\site-packages\jupyter_client\launcher.py", line 115, in launch_kernel
    proc = Popen(cmd, **kwargs)
  File "C:\Users\USER1\Anaconda2\lib\subprocess.py", line 710, in __init__
    errread, errwrite)
  File "C:\Users\USER1\Anaconda2\lib\subprocess.py", line 958, in _execute_child
    startupinfo)
WindowsError: [Error 2] The system cannot find the file specified

我进行了进一步调查，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']

这是个问题，因为我的 python.exe 不在

C:\Users\USER1\Anaconda2_32bit\python.exe

但在

C:\Users\USER1\Anaconda2\python.exe

但是我检查了 Computer/Advanced 系统 settings/Advanced/Enviroment 变量中的路径，\Anaconda2_32bit\ 从未在此处指定。

因此我怀疑在别处指定了错误的路径。这可能在哪里，我该如何解决？

此外，我之前在 \Anaconda2_32bit\ 中安装过 Anaconda，但我已将其卸载。

ipython 在特殊配置文件中注册了内核我有运行命令：

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，发现 python2 的路径设置错误。我已经修复了路径，现在可以使用了。
