尝试为某些数据设置峰值:
import scipy
from lmfit.models import GaussianModel
x = shm.PTR_P
y = shm.PORE_V_P
mod = LorentzianModel()
pars = mod.guess(y, x=x)
out = mod.fit(y, pars, x=x)
print(out.fit_report(min_correl=0.25))
虽然如果我生成数据我可以做到合适,但如果我尝试从其他来源读取它们它就不起作用。我不太擅长这个,也不知道问题是什么。这是输出:

答案 0 :(得分:0)
我猜你的数据中有NaN或者最初的猜测是产生NaNs。 UPDATE DataImport
SET FirstName = initcap(FirstName);
UPDATE DataImport
SET LastName = initcap(LastName);
的初始猜测0似乎是可疑的 - 这应该是> 0。
无论哪种方式,绘制数据并使用sigma
可能有助于隔离问题。
