Scipy fsolve
WebThe function uses scipy.optimize for finding the value that satisfies the power equation. It first uses brentq with a prior search for bounds. If this fails to find a root, fsolve is used. If fsolve also fails, then, for alpha, power and effect_size , brentq with fixed bounds is used. However, there can still be cases where this fails. Web一般处理图片时会转化为double类型。 我们将图片使用scipy保存为pgm格式。 然后我们重新读取该图片信息。 其像素值发生了变化，自动标准化到了0-255范围，最小值变为0，最大值变为255. 所以，使用scipy保存图像时，加上2个参数，cmin和cmax。就可以了 重新读取图片 …
