thanks for making your work public, i follow your instructions but something going wrong.....

Can you try it again to download data.zip, I slightly modify the files ? If you still have this error, you can install the liegroups module, https://github.com/utiasSTARS/liegroups

thanks for replying, we have addressed this issue by your suggestion. But another issue occurs............when we plot figures, something goes wrong....could u please solve this problem. we couldn't find a proper solution in internet to tackle this.......could u please modify the source code 'utils_plot.py' in a more general way.

It seems to be an error with font from latex. I modify the beginning of the file utils_plot.py, that is now

import matplotlib
import os
from termcolor import cprint
import matplotlib.pyplot as plt
import numpy as np
from itertools import chain
from utils import *
from utils_torch_filter import TORCHIEKF

Can you try it ?

It is work, you will probably obtain good results with a possible not so trained filter (flat covariance curve). It is normal, I am waiting for updating the temp.zip file.

[AdamAsh2019]

thanks for your replying, we have addressed it by your instructions!! you guys really did an amazing work! we are looking forward to the new and well trained filter.

[mbrossar]

Now you can download a trained version of the filter.

Can you try it again to download data.zip, I slightly modify the files ? If you still have this error, you can install the liegroups module, https://github.com/utiasSTARS/liegroups

Having a little trouble importing liegroups into the src folder

[wronsky317]

still have this problem, @mbrossar appreciate! with data.zip updated, liegroups installed

    pickle_dict = pickle.load(file_pi)
ModuleNotFoundError: No module named 'liegroups'

by pdb, I find this info:

My fault，ignore this please

restall liegroups solved my trouble

thanks for your sharing!
