I read through the documentation: http://docs.python.org/2/library/time.html#time.strptime and tried datetime . strptime ( date_posted , '%Y-%m-%dT%H:%M:%SZ' ) but I get the error message ValueError: time data '2014-01-15T01:35:30.314Z' does not match format '%Y-%m-%dT%H:%M:%SZ' Any feedback on what is the proper format? I appreciate the time and expertise. 回答1: You can parse the microseconds: from datetime import datetime date_posted = '2014-01-15T01:35:30.314Z'

I usually just use it

Is there an op specifically that does this, or will I need to use some combination of the split/concat type operations? 回答1: All you need to do is a permutation of the dimensions from NHWC to NCHW (or the contrary). The meaning of each letter might help understand: N : number of images in the batch H : height of the image W : width of the image C : number of channels of the image (ex: 3 for RGB, 1 for grayscale...) From NHWC to NCHW The image shape is

There is a question that sounds like this one but it is not the same. 回答1: The result of kl.aggregate(np.sum) is a normal DataFrame, you just have to assign it to a variable to further use it. With some random data: >>> df = DataFrame({'A' : ['foo', 'bar', 'foo', 'bar', >>> 'foo', 'bar', 'foo', 'foo'], ... 'B' : ['one',

However, pandoc replaces $ with \$ and it replaces \ in formulas with \textbackslash{} . Is it possible to get pandoc to pass Mathjax formulas literally from html to latex? 回答1: With the latest version of pandoc (1.12.2), you can do this: pandoc -f html+tex_math_dollars+tex_math_single_backslash -t latex Much nicer! If you don't want to convert math delimited by \( and \) , just do pandoc -f html+tex_math_dollars

In my Unity script, I use, var x = customClass.CallStatic<float>("getHeadX"); In order to get some location data. This method is called per frame to get the updated data (polling method) which makes it inefficient. Instead, I decided to call a C# method in my Unity script from my java code (plugin side) when the updated data is ready. To do this, in my java plugin, I wrote, import com.unity3d.player.UnityPlayer; ... UnityPlayer

I try decoded data with this code: String textoFormado = ...value from MyBatis... ; String s = new String(textoFormado.getBytes("Windows-1252"), "UTF-8"); Almost all the String is correctly decoded. But some letter with acents not. For Example: 回答1: Obviously, textoFormado is a variable of type String . This means that the bytes were already decoded. Java then internally uses a 16-bit Unicode

An unsafe sbyte* pointing to a zero-terminated native string can be converted to a C# string easily, because there is a conversion constructor for this purpose, but I can't find a simple way to convert byte* to byte[] . 回答1: If ptr is your unsafe pointer, and the array has length len , you can use Marshal.Copy like this: byte[] arr = new byte[len]; Marshal.Copy((IntPtr)ptr, arr, 0, len); But I do wonder how you came by an unsafe pointer
