WebJan 31, 2024 · There are 5 basic numerical types representing booleans (bool), integers (int), unsigned integers (uint) floating point (float) and complex. Those with numbers in their name indicate the bitsize of the type (i.e. how many bits are needed to represent a single value in memory). WebApr 8, 2013 · The variable mean_data is a nested list, in Python accessing a nested list cannot be done by multi-dimensional slicing, i.e.: mean_data[1,2], instead one would write mean_data[1][2]. This is becausemean_data[2] is a list. Further indexing is done recursively - since mean_data[2] is a list, mean_data[2][0] is the first index of that list. Web解决方法： 1. 检查输入的数据类型，并确保它们是 NumPy 支持的数据类型。 2. 将输入的数据强制转换为支持的数据类型，例如使用 `numpy.float64`。 3. 使用其他代替函数，例如 `numpy.isinf` 和 `numpy.isnan`，来替代 `isfinite` 函数。 sharon griffin bloomington il
