@Aegaeon I get the same your results with bottleneck...
@shoyer The point is that I haven't decided the use of float32 and — yes — using `.astype(np.float64)` solves the issue...the point is that is not an expected behaviour, with such standard dataset I would not expect any problem related to numerical precision...","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,218459353
