How to use gradient in Numpy
In NumPy, the gradient of an array can be computed using the numpy.gradient function. This function calculates the gradient of an N-dimensional array, and returns a list of N arrays, each of which gives the gradient along a particular dimension. Here is an example of how you can use numpy.gradient to calculate the gradient of Continue reading
How do I change directories using Paramiko?
You can change directories in Paramiko by executing a shell command that changes the current working directory, such as cd or chdir. You can do this by opening a new channel using paramiko.Channel and then executing the shell command using the exec_command method of the channel object. Here’s an example of how you can change Continue reading
How does Django connect to external database?
Django connects to an external database through connection parameters defined in the project’s settings.py file. The DATABASES setting in settings.py defines the database connection parameters, including the database type, the name of the database, the username and password for connecting to the database, and other parameters such as the host, port, and charset. Here’s an Continue reading
