I need to convert that number into a DateTime to query my database (SQL Server). I don't know why, but I can't find a workable answer from a basic google search. (For extra credit, I need to turn my returned DateTime back into a UTC at the end of the day.) This is embarrassing to have to ask such a basic question! :) 回答1: My guess is it's going to be either milliseconds or seconds since a particular epoch - quite possibly the Unix epoch of January 1st

This trivial task that should be completely implicit seems to require a full-blown if / else construction. function IsDowngradeUninstall: Boolean; begin Result := IsCommandLineParamSet('downgrade'); MsgBox('IsDowngradeUninstall = ' + Result, mbInformation, MB_OK); end; This doesn't work because "Type mismatch". IntToStr doesn't accept a Boolean neither. BoolToStr does not exist. 回答1: If you need it once only, the easiest inline solution is to

What I've Tried: I've searched around online and I've seen several similar issues but not mine. I've attempted their solutions including Uninstalling and reinstalling ImageMagick via brew. identify -list format (JPEG, GIF, PNG, TIFF, etc were all there and all had rw permissions) convert -version (png is is among the built-in delegates) convert pic1.png pic1-jpg.jpg (this worked fine) convert pic1-jpg.jpg pic1-jpg.jpg (this worked fine)

How can I convert these to JSON or YAML and HDF5 files which can be used by Keras? I have the code for the Tensorflow model, so it would also be acceptable to convert the tf.Session to a keras model and save that in code. 回答1: Currently, there is no direct in-built support in Tensorflow or Keras to convert the frozen model or the checkpoint file to hdf5 format. But since you have mentioned that you have the code of

My question is: is there any way to implement the function: toBNat :: UNat ->

How can I convert that to the current timezone of the browser? var testDateUtc = moment.tz("2015-01-30 10:00:00", "UTC"); var localDate = ??? So it would be fine if I could find out the users local time zone; or alternatively I'd like to convert the date object into another data object which just uses the "local timezone", no matter what that actually is. 回答1: You do not need to use moment-timezone for this. The
