Python relative import

[mihelog]

This is with Python 3.9 in cygwin. Is it a python version issue?

$ python3 examples/main.py
Traceback (most recent call last):
File "/home/mixel/pymtl3-net/examples/main.py", line 22, in
from meshnet.MeshNetworkCL import MeshNetworkCL
File "/home/mixel/pymtl3-net/build/lib/pymtl3_net/meshnet/init.py", line 1, in

File "/home/mixel/pymtl3-net/build/lib/pymtl3_net/meshnet/MeshNetworkCL.py", line 12, in
from ..ocnlib.cl import BoundaryUnit
ImportError: attempted relative import beyond top-level package

Thanks in advance.

Thanks for the message! The examples/main.py is deprecated and not maintained anymore. I will remove it in the next release to avoid confusion. The new frontend script is script/pymtl3-net. You can try $ python3 script/pymtl3-net -h to see the available options.

Thanks for answering! That works indeed but I wonder if there is a listing of available flags? Looking at the source code I see there are parameters such as the number of virtual channels and size, but I couldn't find how to pass those on to the frontend script. I'm talking about "flags" here:

usage: ./pymtl3-net gen []'

You can also do $ python3 script/pymtl3-net gen -h to see the available topologies for gen. Then say if you want to generate a ring network you can try $ python3 script/pymtl3-net gen ring -h to see the available parameters for the ring network.

Alternatively, you can also create your own python file, import pymtl3_net, instantiate a network module with desired parameters, and apply pymtl3 translation pass to generate the verilog, or apply the simulation pass and create your own simulator.
