deprecation-warning

问题 I am migrating a piece of software from Python 2.7 to Python 3. One problem that arises is: The sklearn.neighbors.kde module is deprecated in version 0.22 and will be removed in version 0.24. The corresponding classes / functions should instead be imported from sklearn.neighbors. Anything that cannot be imported from sklearn.neighbors is now part of the private API. I am not sure which line causes this, and not sure if it is an error or a warning, and what are the implications. On python 2.7

问题 When issuing a statement to MySQL8 server: SELECT SQL_NO_CACHE * FROM <table-name>; I get this warning: Warning, 1681, 'SQL_NO_CACHE' is deprecated and will be removed in a future release. I would like to ask if there is any successor of the SQL_NO_CACHE that works or is planned to work with MySQL 8.x? Does SQL_NO_CACHE actually work with MySQL 8.x or it is omitted by the server? 来源： https://stackoverflow.com/questions/58584596/mysql-8-warning-sql-no-cache-is-deprecated

问题 I've just updated to Django v1.8, and testing my local setup before updating my project and I've had a deprecation warning that I've never seen before, nor does it make any sense to me.

问题 I've just upgraded to PHP 7 and have been hammering out errors associated with deprecated functions, with much success. Sadly, I've been having trouble fixing the new preg replace methodology for my "view php array in a interactive collapsable javascript thing" code. The following code: function print_r_tree($data) { // capture the output of $this->print_r_tree $out = print_r($data, true); // replace something like '[element] => <newline> (' with <a href="javascript:toggleDisplay('...');">...

问题 I have some python code which uses numpy and have run this successfully for a year or more.
