问题 I have a python project, let's call it foobar , there is a setup.py script in project root directory like all Python projects. For example foobar setup.py setup.py file content: from ez_setup import use_setuptools use_setuptools() from setuptools import setup, find_packages setup( name='foobar', version='0.0.0', packages=find_packages(), install_requires=[ 'spam==1.2.3', 'eggs>=4.5.6', ], ) I need to get dependencies information from that setup.py file using Python. The part I want would be [

问题 Whenever I'm trying to open Youtube player in my app, onInitializationSuccess() function is always called. But it shows a blank screen. First this error appears: W/YouTubeAndroidPlayerAPI: Forcefully created overlay:affq@82a17f5 helper:Lazy@9b7098a view:null status: ....... {...} and then: E/YouTubeAndroidPlayerAPI: Embed config is not supported in RemoteEmbeddedPlayer . Here is my code: FragmentManager fragmentManager = ((AppCompatActivity)this.context).getSupportFragmentManager();

问题 How can I upgrade values from a base dataclass to one that inherits from it? Example (Python 3.7.2) from dataclasses import dataclass @dataclass class Person: name: str smell: str = "good" @dataclass class Friend(Person): # ... more fields def say_hi(self): print(f'Hi {self.name}') friend = Friend(name='Alex') f1.say_hi() prints "Hi Alex" random_stranger = Person(name = 'Bob', smell='OK') return for random_stranger "Person(name='Bob', smell='OK')" How do I turn the random_stranger into a

问题 I'm just starting out with the basic concepts OO in PHP, Foo.php class Foo extends Command { public function __construct() { parent::__construct(); } public function fire() { $bar = new Bar(); } } Bar.php class Bar extends Foo { public function __construct() { parent::__construct(); $this->info('Bar'); } } When I run Foo::fire() it gives: Call to undefined method Foo::__construct() . But Foo clearly has a constructor, what am I doing wrong? Another thing I suspect is that it might be a

问题 I have a couple of domain types in my code that I use to distinguish different types of strings, so the compiler can stop me from e.g. passing arguments in the wrong order: type Foo = string type Bar = string let baz (foo : Foo) (bar : Bar) = printfn "%A %A" foo bar let f : Foo = "foo" let b : Bar = "bar" baz f b // this should be OK baz b f // this shouldn't compile However, this currently doesn't work satisfactorily, for two reasons: I haven't been able to figure out a way to specify that

问题 After over a year of development, I have a pretty well developed site. Now I'm going to open it up for a public beta but I need to clear my Firestore of all it's data (it's all test data). Is there a simple way to do this or do I have to delete every single entry by hand? (There are over 1000 entries). The only realistic option I can think of at the moment is to switch Firebase projects to a new one, which is not something I want to do. Solution : After reaching out to Firebase support, I was

问题 This question looks similar to Should my Scala actors' properties be marked @volatile? but not sure that answer will be the same. As example, in case when the fork-join dispatcher was configured and actor's state wasn't marked by @volatile, is it guarantied that state of the actor will be propagated through the cache hierarchy from one core (or processor) to another if fork/join worker threads run on different cores (or processors)? P.S. Is it right that after JSR133 only one write/read

问题 As of python 3.3 the stdlib has the venv module for creating virtual environments. Are python 3.x venv environments relocatable? 回答1: Nope, commands installed in ./bin have fixed paths in shabang lines. 来源： https://stackoverflow.com/questions/27186207/are-python-3-x-venv-environments-relocatable
