TypeError: <lambda>() takes exactly 2 arguments (1 given)

Hello,
wen running run_simcai.py the error in the title is displayed regarding line 181 of RVO.py file.
The code where the error is detected is:
dists = map(lambda p_pw, V_pw: p.linalg.norm(p_pw + V_pw*delta_t - p_pk, order=1), p_pw_V_pw_lst)
Can anyone help me out with this?
Thank you
