Issue with Deinterleave block

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

Sandhya,
one quick question here: Is there really necessity to use 3.6.2
instead of 3.6.5 or 3.7?

Then: Ok, how do you come to the conclusion that sizeof_float would be
right for bytes?
And: I don’t see any C++, where is your C++ problem?
The sizeof_ attributes are members of the gr. module in
python.

Greetings,
Marcus

Because i’am using instant sdr live usb which has come installed with
3.6.2

Well sorry that message was like when i changed the datatype of the
deinterleaved block to float. Now i changed all the blocks datatype to
bytes so the error is
self.blocks_deinterleave_0 = blocks.deinterleave(blocks.sizeof_char*1)
AttributeError: ‘module’ object has no attribute ‘sizeof_char’

Thanks

As I’ve said, sizeof_char is in gr. and not in blocks.

But can you be more clear about it.

Thanks
Sandhya

oops instead of python i mentioned it C++ . Sorry for that .

Thanks

not really:
use gr.sizeof_ instead of blocks.sizeof_ .
