123456789 how is the calculation equal to 1? -The abccsss answer assumes that each number can only appear once. 123456789 how is the calculation equal to 1? -Abccsss answer It is assumed that each number can only appear once. Reply: Mathematica code Relatively simple Det/@N@Range@9~Permutations~{9}~ArrayReshape~{9!,3,3}//Max The above uses Matlab brute-force cracking (enumeration cases). No other cases with the same determinant have been output yet, which seems to be generated in seconds.

operations, such as calculating the sum of all elements of an array, are implemented as methods of The ndarray class. these methods need to be called by instances of The ndarray class during use. >>> a= np.random.random((2,3)) >>> a array([[ 0.65806048, 0.58216761, 0.59986935], [ 0.6004008, 0.41965453, 0.71487337]]) >>> a.sum() 　 3.5750261436902333 >>> a.min() 0.41965453489104032 >>> a.max() 0.71487337095581649 These operations regard arrays as a one-dimensional linear list.

dimension that is missing and/or length 1. The popular point is that the "broadcast dimension" of a smaller array must be 1. Let's take a look at the broadcast on the two-dimensional array. The shape of the arr (4,3), Arr.mean (0) (Ar.mean (index) can be easily understood as flattening the arr, such as shape (m,n,l,... ) Index 1 is processed after the shape is (m,l,... ) has a shape of (3,) that conforms to the broadcast principle and runs as follows: >>> import NumPy as NP >>> Arr=np.arange ()

Python is a common tool for data processing, can handle the order of magnitude from a few k to several T data, with high development efficiency and maintainability, but also has a strong commonality and cross-platform, here for you to share a few good data analysis tools, the need for friends can refer to the next Python is a common tool for data processing, which can handle data ranging from a few k to several T, with high development efficiency and maintainability, as well as a strong versati

, the bigger the money, the better.Power problem: A video card power is close to 300W, four graphics card recommended power over 1500W, in order to expand later, the selection of 1600W power.Chassis heat Dissipation:Because of the size of the various components, a large chassis with good thermal dissipation is required, and the TT Thermaltake Core V51 chassis is selected, with 3 12cm fans as standard. In the future, if necessary, water-cooled equipment can be installed.The above is the main hard

2.7 and 3.5 Two versions of Python were installed on the notebook, and failed to create process error occurred while installing Keras with the 3.5 version of PIP. Here's how to fix it:1. Since I have configured both 2.7 and 3.5 paths in the environment variable, I can execute python3 directly at the command line to start the 3.5 version of Python;2. Start the PIP via Python3, enter the python3-m pip install Keras
