AttributeError: 'Add' object has no attribute 'log' Python
AttributeError: 'Add' object has no attribute 'log' Python
我犯了语法错误，我的语法如何导致 python 认为我在写 +.log 某些地方？
请看一下代码并告诉我。
任何人都可以建议一个可以用来解决这个算法的函数
import numpy as np
import sympy as sp
answer = 0
x = sp.Symbol('x')
y = sp.Symbol('y')
W = sp.Symbol('W')
R = sp.Symbol('R')
a = sp.Symbol('a')
n = sp.Symbol('n')
m = sp.Symbol('m')
O = sp.Symbol('O')
'''
answer = sp.solve(((((-1* (np.log(1+(x/R))))/(np.log(1+((10**6)/R))))+1)*(Os/((np.log(np.exp(1)+(x/a)**n))**m)))-W,x)

我认为你应该使用 sp.log 而不是 np.log。我 运行 你的代码，但似乎方程太复杂了，没有实现算法来解决它。
