If you want to merge your branch to master on remote, follow the below steps: push your branch say ‘br-1’ to remote using git push origin br-1. switch to master branch on your local repository using git checkout master. update local master with remote master using git pull origin master. merge br-1 into local master using git merge br-1. … Read more
0L is a long integer value with all the bits set to zero – that’s generally the definition of 0. The ~ means to invert all the bits, which leaves you with a long integer with all the bits set to one. In two’s complement arithmetic (which is almost universal) a signed value with all bits set to one is -1. The reason for … Read more
ou will also have to look in your system path. Python puts itself there and does not remove itself: http://www.computerhope.com/issues/ch000549.htm Your problems probably started because your python path is pointing to the wrong one.
An <a> element is invalid HTML unless it has either an href or name attribute. If you want it to render correctly as a link (ie underlined, hand pointer, etc), then it will only do so if it has a href attribute. Code like this is therefore sometimes used as a way of making a link, but without having to provide an actual … Read more
Numpy ndarrays are meant for all elements to have the same length. In this case, your second array doesn’t contain lists of the same length, so it ends up being a 1-D array of lists, as opposed to a “proper” 2-D array. From the Numpy docs on N-dimensional arrays: An ndarray is a (usually fixed-size) multidimensional … Read more
uint32_t is a numeric type that guarantees 32 bits. The value is unsigned, meaning that the range of values goes from 0 to 232 – 1. This declares a pointer of type uint32_t*, but the pointer is uninitialized, that is, the pointer does not point to anywhere in particular. Trying to access memory through that pointer will cause … Read more
Python 3.7+ or CPython 3.6 Dicts preserve insertion order in Python 3.7+. Same in CPython 3.6, but it’s an implementation detail. or Older Python It is not possible to sort a dictionary, only to get a representation of a dictionary that is sorted. Dictionaries are inherently orderless, but other types, such as lists and tuples, are … Read more
I think the problem is given in the error message, although it is not very easy to spot: ‘Too many indices’ means you’ve given too many index values. You’ve given 2 values as you’re expecting data to be a 2D array. Numpy is complaining because data is not 2D (it’s either 1D or None). This is a … Read more
Developers are often confused by what a callback is because of the name of the damned thing. A callback function is a function which is: accessible by another function, and is invoked after the first function if that first function completes A nice way of imagining how a callback function works is that it is … Read more
for arrays (which is what you want) or for single elements. But it’s more simple to use vector, or use smartpointers, then you don’t have to worry about memory management. L.data() gives you access to the int[] array buffer and you can L.resize() the vector later. L.get() gives you a pointer to the int[] array.
