[SciPy-User] Can not import sigtools (latest svn, python 3.1)

[Nadav Horesh]

>>> from scipy.signal import sepfir2d
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
from scipy.signal import sepfir2d
File "/usr/lib64/python3.1/site-packages/scipy/signal/__init__.py", line 11, in <module>
from .fir_filter_design import *
File "/usr/lib64/python3.1/site-packages/scipy/signal/fir_filter_design.py", line 6, in <module>
import sigtools

I edited "fir_filter_design.py" and chaned to:

from scipy.signal import sigtools

but then I got the error:

File "/usr/lib64/python3.1/site-packages/scipy/signal/__init__.py", line 7, in <module>
from . import sigtools
ImportError: cannot import name sigtools

I do not know how to fix this. Any ideas?

Most likely a build error: to confirm, please go into the directory
where sigtools.so is located and do a direct import:

python -c "import sigtools"

this should give a better explanation,

cheers,

rm -rf build

and try again? The 2to3 process breaks if you interrupt it.

My mistake was that I did not restart python3 after fixing line 6 of scipy/signal/fir_filter_design.py.
This line should be corrected to:

from . import sigtools

Thank you very much,
