warnings

问题 Hi guys I have this warning on my code. I try to compile using @SuppressWarnings("unchecked") It compile but at the time of the execution the program can't find the main class. How can I solve this problem? Below the code: import java.util.*; @SuppressWarnings("unchecked") class ProgRub { public static void main(String argv[]) { Hashtable rubrica = new Hashtable(20); String chiave, valore; Menu mioMenu = new Menu(); int scelta; scelta = (int) mioMenu.scelta(); while (scelta != 5) { if (scelta

问题 I am using Anaconda and I am trying logistic regression. After loading training data set and performed the regression. Then I got the following warning message. train_cols = data.columns[1:] logit = sm.Logit(data['harmful'], data[train_cols]) result = logit.fit() Warning: Maximum number of iterations has been exceeded. Current function value: 0.000004 Iterations: 35 C:\Users\dell\Anaconda\lib\site-packages\statsmodels\base\model.py:466: ConvergenceWarning: Maximum Likelihood optimization

问题 Is there any way to promote all mysql warnings to fatal errors? I'd like to avoid any data truncation (including fractional parts). 回答1: In some modes, MySQL raises warnings instead of the errors that are required by the SQL Standard. You certainly want to raise an error when significant data is removed, but you probably don't want an error raised when a COUNT(colname) expression finds some rows with nulls in the column and ignores them for counting purposes (a Standard warning). As MySQL

问题 I use Object.freeze as a means to prevent myself from breaking my own rules. I would like Object.freeze to speak to me when I try to make a bad assignment. However, Object.freeze simply makes the assignments silently fail! For example, if I do /* * Frozen singleton object "foo". */ var foo = (function() { var me = {}; me.bar = 1; if (Object.freeze) { Object.freeze(me); } return me; })(); foo.bar = 2; console.log(foo.bar); the console will log "1", but I won't know that I ever made a bad

问题 In newer versions of R (I have 3.6 and previously had 3.2), the stats::regularize .values function has been changed to have a default value of warn.collapsing as TRUE. This function is used in splinefun and several other interpolation functions in R. In a microsimulation model, I am using splinefun to smooth a large amount (n > 100,000) of data points of the form (x, f(x)). Here, x is a simulated vector of positive-valued scalers, and f(x) is some function of (x). With an n that large, there
