error initializing a nco object

[kawtherOuenniche]

Hi, I'm trying to use nco on google colab but when I iniatialize the object nco = Nco() it raises the error

/usr/local/lib/python3.6/dist-packages/nco/nco.py in init(self, returnCdf, return_none_on_error, force_output, cdf_module, debug, **kwargs)
56 self.nco_path = os.environ["NCOpath"]
57 else:
---> 58 self.nco_path = os.path.split(distutils.spawn.find_executable("ncks"))[0]
59
60 self.operators = operators

/usr/lib/python3.6/posixpath.py in split(p)
105 """Split a pathname. Returns tuple "(head, tail)" where "tail" is
106 everything after the final slash. Either part may be empty."""
--> 107 p = os.fspath(p)
108 sep = _get_sep(p)
109 i = p.rfind(sep) + 1

TypeError: expected str, bytes or os.PathLike object, not NoneType

What am I supposed to do ?

I have the same exact issue and am not coming up with a solution as of yet. Trying to import it into a Jupyter Notebook using python, but same exact error and nco=Nco() operator after importing nco.

I am not very familiar with these issues, but this discussion seems relevant: https://stackoverflow.com/questions/68227959/error-using-nco-in-jupyter-notebook-not-loading-gives-error-typeerror-after-co
I suggest setting NCOpath to the directory of ncks on your system with, e.g.,
export NCOpath='/usr/local/bin'
Perhaps @hmb1 has an idea too...

Thanks @czender, that stack discussion is actually my discussion. The ncks seems to be only contained inside my conda environment. Does that need to be installed somewhere else? I set the path as you suggested but still no luck.

I think NCO and pyNCO are separate installations. Did you install NCO? If so, then pyNCO should find it if you set NCOpath to the directory containing the ncks executable.
