I came here because the title of this topic does not mention Docker. I had the same problem when using the application BlueStacks in Windows 10, without Docker. Windows did not shut down (or took a long time to do so) because ‘VirtualBox still has active connections’. I’d like to share my solution here, using … Read more
1170 pip is just a PyPI package like any other; you could use it to upgrade itself the same way you would upgrade any package: On Windows the recommended command is:
Maybe you just need to commit. I ran into this when I did: Oops! Never committed! All I had to do was: Success!
Perhaps the error message is somewhat misleading, but the gist is that X_train is a list, not a numpy array. You cannot use array indexing on it. Make it an array first:
Your header file Hash.h declares “what class hash should look like”, but not its implementation, which is (presumably) in some other source file we’ll call Hash.cpp. By including the header in your main file, the compiler is informed of the description of class Hash when compiling the file, but not how class Hash actually works. When the linker tries to create the entire program, … Read more
It’s pretty simple really: There is also the step value, which can be used with any of the above: The key point to remember is that the :stop value represents the first value that is not in the selected slice. So, the difference between stop and start is the number of elements selected (if step is 1, the default). The other feature is that start or stop may be a negative number, which … Read more

There is no “standard android dialing pad”. Every phone ships their own dialer, which may or may not be the one google wrote. There is no dialing pad widget. You can ask for a numeric keyboard and force the keyboard to show, but it may have any format, and may not just be those 9 … Read more
The Python approach to “main” is almost unique to the language(*). The semantics are a bit subtle. The __name__ identifier is bound to the name of any module as it’s being imported. However, when a file is being executed then __name__ is set to “__main__” (the literal string: __main__). This is almost always used to separate the portion of code which should … Read more
For custom-delimited date formats, you have to pull out the date (or time) components from a DateTimeFormat object (which is part of the ECMAScript Internationalization API), and then manually create a string with the delimiters you want. To do this, you can use DateTimeFormat#formatToParts. You could destructure the array, but that is not ideal, as the array output depends … Read more
