Windows: ipykernel install prefix not usable for c:\programdata\jupyter #1234
Description
On windows jupyter --paths gives
jupyter --paths
config:
C:\tools\miniconda3\envs\pytorch\etc\jupyter
C:\Users\Administrator\.jupyter
C:\Users\Administrator\AppData\Roaming\Python\etc\jupyter
C:\ProgramData\jupyter
data:
C:\tools\miniconda3\envs\pytorch\share\jupyter
C:\Users\Administrator\AppData\Roaming\jupyter
C:\Users\Administrator\AppData\Roaming\Python\share\jupyter
C:\ProgramData\jupyter
runtime:
C:\Users\Administrator\AppData\Roaming\jupyter\runtimeAnd I'd like to use C:\ProgramData\jupyter to store kernelspecs from various different kernels from different envs (using miniconda at the moment)
Trying to do that...
(pytorch) PS C:\Users\Administrator> python -m ipykernel install --name pytorch --prefix=C:\ProgramData\jupyter

[InstallIPythonKernelSpecApp] WARNING | Installing to C:\ProgramData\jupyter\share\jupyter\kernels, which is not in ['C:\\tools\\miniconda3\\envs\\pytorch\\share\\jupyter\\kernels', 'C:\\Users\\Administrator\\AppData\\Roaming\\jupyter\\kernels', 'C:\\Users\\Administrator\\AppData\\Roaming\\Python\\share\\jupyter\\kernels', 'C:\\ProgramData\\jupyter\\kernels', 'C:\\Users\\Administrator\\.ipython\\kernels']. The kernelspec may not be found.
Installed kernelspec pytorch in C:\ProgramData\jupyter\share\jupyter\kernels\pytorchso somewhere (took a quick look at the code could only find a test that seemed to assume it would) "share" and "jupyter" added into prefix path before "kernels" so this kernel is not found.
moving C:\ProgramData\jupyter\share\jupyter\kernels\pytorch to C:\ProgramData\jupyter\kernels\pytorch means it gets found
perhaps a --raw-prefix, to which I'd pass C:\ProgramData\jupyter\kernels\ to, that left the prefix as given would solve this?
