Generally tf.gather gives you access to elements in the first dimension of a tensor (e.g. rows 1, 3 and 7 in a 2-dimensional Tensor). If you need access to any other dimension than the first one, or if you don't need the whole slice, but e.g. only the 5th entry in the 1st, 3rd and 7th row, you are b...

Sometimes Android's logcat is running infinitely with errors coming from some process not own by you, draining battery or just making it hard to debug your code.
A convenient way to fix the problem without restarting the device is to locate and kill the process causing the problem.

You can use Scan or TryScan methods to look for specific messages in the queue and process them regardless of how many messages are before them. Both methods look at the messages in the queue in the order they arrived and will look for a specified message (up until optional timeout). In case there i...
To count the occurences of a value in a numpy array. This will work:
>>> import numpy as np
>>> a=np.array([0,3,4,3,5,4,7])
>>> print np.sum(a==3)

The logic is that the boolean statement produces a array where all occurences of the requested values are 1 and all o...
You can use cell references without row numbers.
For instance, the formula =sum(C:C) will add up all the values in column C of the active sheet. This is helpful when you are adding and removing rows but don't want to update your formulas each time.
There are some instances when using this whole co...

One of the most critical parts of dealing with NMS code is being able to support mulitple Minecraft versions. There are numerous ways to do this, but a simple solution is to use this code to store the version as a public static field:

Weak references are... references, to other objects (aka "targets"), but "weak" as they do not prevent those objects from being garbage-collected. In other words, weak references do not count when the Garbage Collector evaluates objects as "live" or "dead".
