I use the `get_group` function and solve my problem.  But a warning arises at the line `if name not in self.groups:` as: `DeprecationWarning: elementwise comparison failed; this will raise an error in the future`.

When the group contains nothing, I may assign `nan` or `0` to the corresponding bin.  If it is dropped silently, then I need to find out which bin is missing its group.  I like this PR #1027 by Ryan with a kwarg `drop_empty_bins` but not sure this option is eventually merged into master or not.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,607718350

But I don't want aggregation operations here.  I need the samples in each group to index another array.  Maybe this is not the best solution.  But my case do need all the groups in the same order as the given bins, including possible empty ones.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,607718350
