Python does not allow ! in function names, so this is also a limitation of pyjulia To use functions which on the Julia side have a !, like step!, replace ! by _b, for example:from diffeqpy import de def f(u,p,t): return -u u0 = 0.5 tspan = (0., 1.) prob = de.ODE...

$$\omega^{t} = \omega^{t - 1} + \eta \frac{{m^{t} }}{{\sqrt {\upsilon^{t} } + \tau }}$$ (8) where \({\omega }_{FedAvg}^{t}\) denotes the aggregated weights by FedAvg, \({\omega }^{t-1}\) is the global model weights after training round t−1, \({\bet...
若满足条件 \begin{cases} p_{out} \le \sqrt{\displaystyle\frac{(n_i-1)\ln{n}}{n\ln{n_i}}} \\ p_{in}^{(i)}n_i+p_{out} \gt \displaystyle\frac{8}{3} \end{cases} \\则以下结论几乎必然(有 100% 的把握)成立: \kappa(x_{B_i},y_{B_i}) \ge \displaystyle\frac{(n_...
I recently ran into an issue whereby curve_fit was failing to fit a function, even though the guesses were reasonable. The warning reported by Scipy was "/usr/local/depot/Python-3.5.1/lib/python3.5/site-packages/scipy/optimize/minpack.py...
