A buffer of decoders for multiple generations

[Ahmad Alhilal]

I'm using kodo-python library in my project. I need to use a buffer of decoders for multiple generations, where  the decoder is like:
decoder = kodo.RLNCDecoder(
field=kodo.field.binary8,
symbols=rlncPacket.symbols,
symbol_size=self.args.symbol_size)

frame_length = rlncPacket.symbols
data_out = bytearray(decoder.block_size())

decoder.set_symbols_storage(data_out)

I tried dictionary to save decoder and data_out object but I got stack overflow, although I was making sure to delete on generation completion.

# empty dictionary

my_dict = {}

my_dict[gen_no] = [decoder, data_out]

del my_dict[gen_no] #on completion

Have you tried any solution that works well for you?
Could you please share your experiences?
