问题遇到的现象和发生背景
使用python中optimize.curve_fit函数对曲线拟合的时候，出现Residuals are not finite in the initial point报错，请问该怎么处理啊？
问题相关代码，请勿粘贴截图
popt, pcov = optimize.curve_fit(get_all_SEIR, init_SEIR_num, infectious, bounds=([-1,0,0,0,0,1],[1,0.5,0.5,0.5,0.5,5]),maxfev=500000)
运行结果及报错内容
popt, pcov = optimize.curve_fit(get_all_SEIR, init_SEIR_num, infectious, bounds=([-1,0,0,0,0,1],[1,0.5,0.5,0.5,0.5,5]),maxfev=500000)
