@ozzyw:matrix.orgozzywthanks! I forked my suggested changed. was just a slight tweak on the summation indices I think they were wrong20:33:29
@shreyasbapat:matrix.orgshreyasbapatSure. Did you create a Pull Request?20:38:26
@ozzyw:matrix.orgozzywsorry, new to github, just figuired it out and submitted the request 20:43:27
@shreyasbapat:matrix.orgshreyasbapatNo worries at all 😄20:45:13
@shreyasbapat:matrix.orgshreyasbapatWe are all new here. Thanks for the help20:45:22
@shreyasbapat:matrix.orgshreyasbapatI will review #573 and let you know 😄20:46:31

@ozzyw:matrix.orgozzywHey there, I am working on a research project using einsteinpy. There were a lot of invariants that I needed that were not supported by einsteinpy.symbolic. so so far I've added 4 ricci invariants and 2 Weyl invariants. I will likely be adding all the Zakhary Mcintosh scalars as I go. I've also created a separate BaseRelativityScalar class similar to the Tensor one. Are these within the intended scope of that module? If so I'd like to make a pull request once I've done more testing. I feel like this would be useful functionality for other metric analysis projects. 00:19:48

Hey ozzyw.. The aim of the Symbolic module is to help theoretical physicists with symbolic calculations and these do sound like some useful and exciting additions. Please open a PR, whenever you are ready. 😄

@amar123:matrix.orgamar123 cannot import name 'four_position' from 'einsteinpy.coordinates.utils' (C:\Users\Lenovo\Anaconda3\lib\site-packages\einsteinpy\coordinates\utils.py) I found this error on import and i checked out the utils.py there is no any function name four_position on the utils.py file . but there is example given with this import 11:07:26

@amarghimire-6044b4586da037398465cfff:gitter.imamarghimire (Amar Raj Ghimire) from einsteinpy.coordinates.utils import four_position, stacked_vec I have checked the utils.py file but it doesnt contain any class / function named four_postion but I couldnt import "four_position" as on the suggested demo code of schwarzschild metric on einsteinpy doc . 11:37:27
