python - 为什么 binned_statistic_2d 现在抛出 TypeError？

Question

我一直在使用 scipy 的 binned_statistic_2d 函数来绘制一些数据的二维直方图，特别是通过设置 expand_binnumbers = True 来返回数据所在 bin 的索引列表。直到今天，它都运行良好。以下代码演示了我的问题:

import numpy as np
from scipy.stats import binned_statistic_2d as hist 

# my data is two arrays of numbers 
x = np.random.random((5,))
y = np.random.random((5,))

# I need to know which bin the values are in so I return the bin_idx
data = hist(x,y, bins = [2,2], statistic = 'count', values = None, expand_binnumbers = True)

bin_idx = data[3]

TypeError: ufunc 'isfinite' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

任何想法为什么这应该突然停止工作？

Scipy 最近的更新在某种程度上破坏了事情 - 正如@WarrenWeckesser 在评论中所说，设置 values = x 使事情再次工作。
