Any Python file is a module, its name being the file’s base name without the .py extension. A package is a collection of Python modules: while a module is a single Python file, a package is a directory of Python modules containing an additional __init__.py file, to distinguish a package from a directory that just … Read more
The difference between tf.keras and keras is the Tensorflow specific enhancement to the framework. keras is an API specification that describes how a Deep Learning framework should implement certain part, related to the model definition and training. Is framework agnostic and supports different backends (Theano, Tensorflow, …) tf.keras is the Tensorflow specific implementation of the … Read more
Hadoop is basically 3 things, a FS (Hadoop Distributed File System), a computation framework (MapReduce) and a management bridge (Yet Another Resource Negotiator). HDFS allows you store huge amounts of data in a distributed (provides faster read/write access) and redundant (provides better availability) manner. And MapReduce allows you to process this huge data in a … Read more
You could filter the keys (assuming same keys) by checking the unequal value. var obj1 = { prop1: false, prop2: false, prop3: false }, obj2 = { prop1: false, prop2: true, prop3: false }, difference = Object.keys(obj1).filter(k => obj1[k] !== obj2[k]); console.log(difference);
any() checks absolutely nothing. Since Mockito 2.0, any(T.class) shares isA semantics to mean “any T” or properly “any instance of type T“. This is a change compared to Mockito 1.x, where any(T.class) checked absolutely nothing but saved a cast prior to Java 8: “Any kind object, not necessary of the given class. The class argument … Read more
You can use sort_values with groupby and aggregating diff: df[‘diff’] = df.sort_values([‘id’,’time’]).groupby(‘id’)[‘time’].diff() print (df) id time diff 0 A 2016-11-25 16:32:17 NaT 1 A 2016-11-25 16:36:04 00:00:35 2 A 2016-11-25 16:35:29 00:03:12 3 B 2016-11-25 16:35:24 NaT 4 B 2016-11-25 16:35:46 00:00:22 If need remove rows with NaT in column diff use dropna: df = … Read more
In head recursion, the recursive call, when it happens, comes before other processing in the function (think of it happening at the top, or head, of the function). In tail recursion, it’s the opposite—the processing occurs before the recursive call. Choosing between the two recursive styles may seem arbitrary, but the choice can make all … Read more
Another option, for more sophisticated difference checking, is to make use of the PatienceDiff algorithm. I ported this algorithm to Javascript at… https://github.com/jonTrent/PatienceDiff …which although the algorithm is typically used for line-by-line comparison of text (such as computer programs), it can still be used for comparison character-by-character. Eg, to compare two strings, you can do … Read more
You can use the difference method provide by DateTime class //the birthday’s date final birthday = DateTime(1967, 10, 12); final date2 = DateTime.now(); final difference = date2.difference(birthday).inDays; UPDATE Since many of you reported there is a bug with this solution and to avoid more mistakes, I’ll add here the correct solution made by @MarcG, all … Read more
Those are two completely different things: An Activity is an application component that provides a screen, with which users can interact in order to do something. More details: https://developer.android.com/guide/components/activities/intro-activities Whereas a Fragment represents a behavior or a portion of user interface in an Activity. https://developer.android.com/guide/fragments
