Am getting the following error when trying to run a GRC flowgraph that loads FFT filter taps from an external file. The type filter parameter is set to complex->complex (complex taps).
The flow graph has imported numpy. The taps are loaded using:
numpy.fromfile('/home/tom/Desktop/EchoScreencaps/chirp-down-20-20-131072', numpy.complex64)
as the taps parameter. What does the error below mean?
GRC: v3.7.4git-101-g76970d54
Ubuntu 13.10
top_block.py is attached.
