I've been running into bugs trying to model symmetric distance matrices using the same dimension. Interestingly, it does work very well for selecting, e.g. if use `.sel(nodes=node_list)` on a square matrix i correctly get a square matrix subset 👍 But unfortunately a lot of other things seems to break, e.g. concatenating fails with `ValueError: axes don't match array` :( What would need to happen to make this work?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,222676855
