比如:字符串"helloworld"和"loop"的最长公共子序列为loo;字符串acdfg与adfc的最长公共子序列为adf。 注意:区别最长公共子串,最长公共字串要求连续,而序列可以不连续。 def LCSubsequence(string1,string2): len1 = len(string1) len2 = len(string2) res = [[0 for i in range(len1+1)] for j in r...

Cellpose 2.0 now allows human-in-the-loop training of models! To learn more... Check out the twitter thread for an overview. Check out the paper for more details on the algorithm and the performance. Also, there's a short review of the paper available here. Watch the short intro talk ...
Option 2: Installation Instructions with python's venv Venv (tutorial, for those interested) is a built-in tool in python for creating virtual environments. It is a good alternative if you don't want to install conda and already have python3 on your machine. The main difference is that you...

discord.py wait_for not working in a method I have 2 separate files in this case, where 1 is for the main file, and another is a file containing functions(not in a Cog). I want to have a user respond to the message that a bot outputs and then t......
In following program, what is the purpose of the while loop? There are no problems with the compilation, but whether or not I have the while loop in place or not, the result is the same. I can't understand why the while loop is included. BTW, this is just an ex......
Finally, on lines 52 to 70, you implement the for loop for the stochastic gradient descent. It differs from gradient_descent(). On line 54, you use the random number generator and its method .shuffle() to shuffle the observations. This is one of the ways to choose minibatches randomly....
#Whenever there is a match or the loop is running for the first #time, populate the window using weakchecksum instead of rolling #through every single byte which takes at least twice as long. window=collections.deque(bytes(datastream.read(blocksize))) ...
