ModuleNotFoundError: No module named 'liegroups' about ai-imu-dr HOT 8 CLOSED

Now you can download a trained version of the filter.

from ai-imu-dr.

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

from ai-imu-dr.

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.

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.

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

from ai-imu-dr.

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

    pickle_dict = pickle.load(file_pi)

My fault，ignore this please

restall liegroups solved my trouble

thanks for your sharing!
