TL;DR Summary
Need packages for tensor calculation in differential geometry for mathematica
Hello. I am doing tensor calculation with indices, such as contraction, lowering or raising indices, tensor production, etc.

I have tried the Ricci.m from https://sites.math.washington.edu/~lee/Ricci/

However, maybe because the package has not been upgraded for some time, I could not get the proper output in Mathematica v12.

Do you know other package? Thanks!
