在Python编程中,特别是在使用NumPy库或Pandas库进行数据处理时,我们可能会遇到convert.toInt32报错,这个错误通常发生在我们试图将数据类型从浮点型(float)或其他类型转换为整型(int32)时,以下是对这一问题的详细解析: (图片来源网络,侵删) 需要指出的是,标准的Python类型转换函数如int()并不直接支持转换为特定的整型...

本来inst_com生成了一个细胞的质心,但是不知道什么原因这个质心是NaN,查找了半天也找不到原因只能尝试把这样的细胞过滤掉(因为也不知道具体是哪个细胞)。 # 报错位置inst_com[0]=int(inst_com[0]+0.5)inst_com[1]=int(inst_com[1]+0.5) 二、尝试解决 试了一些判断方法,无论是使用python内置的nan还是np.n...
你可以使用numpy.ndarray.astype()方法来强制转换数组的数据类型。例如: import numpy as np # 创建一个包含字符串的NumPy数组 arr = np.array(['1', '2', '3']) # 强制将数组转换为整数类型 arr_int = arr.astype(int) 在上面的例子中,我们创建了一个包含字符串的NumPy数组,并使用astype()方法将其转...
