28 дек. 2020 г. · The warning tells you it's creating an object dtype array. The elements are not simple numbers. Did you look at the X or it's elements? At its shape and dtype?

8 авг. 2016 г. · I'd like to force lstsq() to return a set of positive values as a solution of the fitting. Is it possible to do this?

14 янв. 2020 г. · The previous default of -1 will use the machine precision as rcond parameter, the new default will use the machine precision times max(M, N).

13 янв. 2017 г. · Notice that numpy's default value for rcond is -1 : negative values refers to machine precision. See this course for the logic. According to the ...
