demo_wavelets bug: Wk.synthesis(S) #1

Closed donnate closed 7 years ago

donnate commented 7 years ago

Hello!

I have just downloaded the package using pip install, and I have been trying to reproduce the code as shown on the Graphlet tutorial, but I keep encountering the same error when trying to place a Kronecker signal at a specific vertex by running: Sf = Wk.synthesis(S)

Error: cheb_coeffs = operator.compute_cheby_coeff(self, m=order, N=order + 1) AttributeError: 'module' object has no attribute 'compute_cheby_coeff'.

It seems that the code calls the function filter.py, which, at line 221, calls: cheb_coeffs = operator.compute_cheby_coeff(self, m=order, N=order + 1) whereas it should probably call: cheb_coeffs = fast_filtering.compute_cheby_coeff(self, m=order, N=order + 1) (seems to work after correcting like this at least...) I was thus wondering if the toolbox had been updated and if something had perhaps changed? Thanks for your time and help.

C.D.

Details: anaconda/python2.7; Mac OS Sierra 10.12.3

Hello,

The devel branch has been updated to fix this typo following code rearrangement. Thank you for the notice!
