The cmake_minimum_required() function is used to avoid any cryptic error messages due to the CMakeLists.txt assuming a later version of CMake than the one installed on the current host. As an example, failing early, and with a clear message… CMake 3.2 or higher is required. You are running version 2.8.12.2 …is to be preferred over … Read more
Yes, -Float.MAX_VALUE is the negative number with largest magnitude. floats are represented the same way as doubles, just with half the storage space (and the accompanying loss of precision.) Since signs in IEEE 754 are represented by a single bit, flipping that bit doesn’t change the overall magnitude attainable by the remaining bits.
If you call arr.argsort()[:3] It will give you the indices of the 3 smallest elements. array([0, 2, 1], dtype=int64) So, for n, you should call arr.argsort()[:n]
Use np.minimum: In [341]: df[‘MinNote’] = np.minimum(1,df[‘note’]) df Out[341]: session note minValue MinNote 0 1 0.726841 0.726841 0.726841 1 2 3.163402 3.163402 1.000000 2 3 2.844161 2.844161 1.000000 3 4 NaN NaN NaN Also min doesn’t understand array-like comparisons hence your error
Python has a min() built-in function: >>> darr = [1, 3.14159, 1e100, -2.71828] >>> min(darr) -2.71828
None is being returned >>> print min([None, 1,2]) None >>> None < 1 True If you want to return 1 you have to filter the None away: >>> L = [None, 1, 2] >>> min(x for x in L if x is not None) 1
Is there a way to only specify only a minimum length? Perhaps another attribute i can use? Using the standard data annotation, No. You must specify the MaximumLength. Only the other parameters are optional. In such a case, I’d recommend something like this: [StringLength(int.MaxValue, MinimumLength = 7)] You can also use a Regex (regular expression) … Read more
I’ve noticed in both Firefox and Chrome that if you set the HTML5 doctype there’s a minimum line-height for inline elements. For block elements you can set the line-height to whatever you want, even make the lines overlap. If you don’t set the HTML5 doctype, there’s no minimum line-height for either block or inline elements.
