vispy.util.logs module#

class vispy.util.logs.NumPyJSONEncoder(*, skipkeys=False, ensure_ascii=True, check_circular=True, allow_nan=True, sort_keys=False, indent=None, separators=None, default=None)#

Bases: JSONEncoder

default(obj)#

Implement this method in a subclass such that it returns a serializable object for o, or calls the base implementation (to raise a TypeError).

For example, to support arbitrary iterators, you could implement default like this:

def default(self, o):
    try:
        iterable = iter(o)
    except TypeError:
        pass
    else:
        return list(iterable)
    # Let the base class default method raise the TypeError
    return JSONEncoder.default(self, o)

vispy.util.logs.log_exception(level='warning', tb_skip=2)#

Send an exception and traceback to the logger.

This function is used in cases where an exception is handled safely but nevertheless should generate a descriptive error message. An extra line is inserted into the stack trace indicating where the exception was caught.

Parameters:

levelstr: See set_log_level for options.
tb_skipint: The number of traceback entries to ignore, prior to the point where the exception was caught. The default is 2.

vispy.util.logs.set_log_level(verbose, match=None, return_old=False)#

Convenience function for setting the logging level

Parameters:

verbosebool, str, int, or None: The verbosity of messages to print. If a str, it can be either DEBUG, INFO, WARNING, ERROR, or CRITICAL. Note that these are for convenience and are equivalent to passing in logging.DEBUG, etc. For bool, True is the same as ‘INFO’, False is the same as ‘WARNING’.
matchstr | None: String to match. Only those messages that both contain a substring that regexp matches 'match' (and the verbose level) will be displayed.
return_oldbool: If True, return the old verbosity level and old match.
