Hi i’ve attempted this with pandas by creating a distance matrix of all the 1 mil locations (so a symmetric matrix of 1 million by 1 million) needless to say it does not work as it is too big for pandas 🙁

Trying to find an alternative to this. Have tried dask and Vaex but am struggling. Can i get some help please? WHat would you use if you had to create a distance matrix to calculate pairwise distances between > 1 mill of locations

Ideally a distance matrix of pairwise distances
