如何用已知的较好参数初始化种群

现在我有一组较好的参数，比如一组维度为(50,10)的numpy数组，其中元素都是float类型，其中50是种群大小，10是参数的维度，我可以用这个数组去初始化种群吗？如何实现呢？
我试过令self.Chrom=这个数组，但是在某个地方报错数据类型不支持，这个self.Chrom必须是int类型的numpy数组吗

Start by tracing where self.Chrom is initialized and where its dtype is assumed, using the reported (50,10) float NumPy array as the case to follow. Done means determining whether a supplied float population is supported and documenting or exposing the required initialization behavior without the reported type error.
