在 Windows 7 64 位上运行 ipyhton 笔记本并使用 python 2 内核启动笔记本时出现错误:

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))

model = sm.create_session(path=path, kernel_name=kernel_name)

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

我已进一步调查,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']

这是一个问题,因为我的 python.exe 不在

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

但在

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

但是我已经检查了计算机/高级系统设置/高级/环境变量中的路径,并且从未在此处指定 \\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?

另外,我之前在 \\Anaconda2_32bit\\ 中安装了 Anaconda,但我已经卸载了它。

最佳答案

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,为 python2 设置了错误的路径。我已经修复了路径,现在可以使用了。
