Normally the return value of `argmax` is an integer dtype array, but NaN isn't a valid integer :(

My suggestion would be to add an optional `fill_value` argument, similar to the API under discussion for `idxmax` in https://github.com/pydata/xarray/pull/3871. If `fill_value` is specified (e.g., with `fill_value=np.nan` or `fill_value=-1`) then missing values are returned with the fill value instead of raising an error.","{""total_count"": 2, ""+1"": 2, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,587062505
