recordio.pack and unpack of header inconsistency (outputting wrong result) #20037

Open pultarmi opened 3 years ago

pultarmi commented 3 years ago

Description

mxnet.recordio.pack followed by mxnet.recordio.unpack is returning wrong result.

Input: HEADER(flag=2, label=17672687.0, id=0, id2=0)

Expected output: HEADER(flag=2, label=17672687.0, id=0, id2=0)

Actual output: HEADER(flag=0, label=17672688.0, id=0, id2=0)

To Reproduce

import mxnet as mx

header = mx.recordio.IRHeader(flag=2, label=17672687.0, id=0, id2=0) s = mx.recordio.pack(header, b'') header = mx.recordio.unpack(s)[0] print('original header ', header) print('header packed and unpacked', header)

What have you tried to solve it?

Tried different versions of Python (3.9.0, 3.8.3, 3.6.13) and of mxnet (mxnet==1.7.0.post1 and mxnet==1.5.0)

Environment

Python 3.9.0, mxnet==1.7.0.post1
