mergevec.py for Python 3.x

[rejaverion]

Hi. When I try to execute mergevec.py the shell returns TypeError: 'str' does not support the buffer interface" for lines 170 and 120

Turns out there is a distinct incompatibilty between Py 2.x and 3.x that causes this error. How do I modify the py script to make it compatible with my Python 3.4?

I got the solution. Python 3,x treats unicode string and byte string differently. So you would need to edit the py script and change 'str' data types to 'bytes'

Hi @rejaverion, I'm no Python expert: how exactly would one solve this issue then? I get the following error when trying to run the mergevec.py script with Python 3.6 (on Windows x64):

Traceback (most recent call last):
  File "tools/mergevec.py", line 170, in <module>
    merge_vec_files(vec_directory, output_filename)
  File "tools/mergevec.py", line 120, in merge_vec_files
    val = struct.unpack('<iihh', content[:12])
TypeError: a bytes-like object is required, not 'str'

Are we having the same issue?
Changing the str( to bytes( on lines 119, 132 and 156 doesn't solve my issue.

It would be a great idea if this repository offered the mergevec.py both for Python 2.x and 3.x, that way nobody runs into this issue again.

Hi,
I'm facing the same issue, any idea on how to solve this? @rejaverion @Timebutt

Hi @rrphotosoft, if I recall correctly I just installed Python 2.7 and ran it with that Python version. There are plenty of other libraries that don't support Python 3 yet anyway, so I'd say it really is a necessity to have both version on your development machine ;)
