请问加控制变量后不收敛的问题您解决了吗？

您好，请问加控制变量后不收敛的问题您解决了吗？

各位大佬哥哥姐姐们，请问最后一期被omitted了以及加入控制变量后不收敛是什么原因，以及该如何解决呀
Warning: suppressing the following coefficients because FE could not be imputed for any units: tau3.
Warning: part of the sample was dropped for the following coefficients because FE could not be imputed: tau0 tau1 tau2.
WARNING: suppressing the following coefficients from estimation because of insufficient effective sample size: tau3. To report them nevertheless, set the minn option to a smaller number or 0, but keep in mind that the estimates may be unreliable and their SE may be downward biased.

Convergence of standard errors is not achieved for coefs: __w_tau0 __w_tau1 __w_tau2.
Try increasing the tolerance, the number of iterations, or use the nose option for the point estimates without SE.
