[Discuss-gnuradio] Issue with Deinterleave block

[Sandhya G]

Hi

   I was just trying to use interleave and deinterleave blocks. GNU radio installed is 3.6.2

flowchar is something like

 vector source ---->

                              interleave ---->throttle--->deinterleave --->scope sink 

vector source ----->

The datatype is byte. when execute the flowchart i'am getting error    

self.blocks_deinterleave_0 = blocks.deinterleave(blocks.sizeof_float*1)
AttributeError: 'module' object has no attribute 'sizeof_float'. May be the error might be simple but i'am very new to C++ .

please help me to solve the issue

Thanks

Sandhya
