error: 'upfirdn' undefined near line 121, column 121

I call the resample .m in python using oct2py, but this error occurred, but upfirdn.oct existed. Is there any solution?

Hi @Xluo-lc, I'm not sure. I just tried with GNU Octave, version 6.4.0 on MacOS, and running the following works:

>>> from oct2py import octave
>>> octave.eval('pkg install -forge signal')
>>> octave.eval('pkg load signal')
>>> octave.upfirdn([1], [1], [1], [1])
1.0

Are you able to run upfirdn from Octave itself?

[Xluo-lc]

I can use upfirdn in octave

But I can't use upfirdn in python

I solved this problem by adding the path. Why can't oct2py find upfirdn?

I'm guessing the launcher used on Windows does some PATH changes for you that aren't handled when you use the EXE. I am not a Windows user.
