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:


as the taps parameter. What does the error below mean?

GRC: v3.7.4git-101-g76970d54
Ubuntu 13.10 is attached.
