Be careful! The list of list is modified unexpected, python # code patch A: list = [1,2,3,4,5,6,7] print('list A :', list) for i in list: temp = i if i > 5: temp = i + 10000 print('list A\':', list) # code patch B: list = [[1],[2],[3],[4],[5],[6],[7]] new_list = [] print('\nlist B : ',list) for i in list: temp = i # will this allocate a new RAM space for var 'temp'? if i[0] > 5: temp[0] = i[0] + 1000 new_list.

python程序运行中改变环境变量: Trying to change the way the loader works for a running Python is very tricky; probably OS/version dependent; may not work. One work-around that might help in some circumstances is to launch a sub-process that changes the environment parameter using a shell script and then launch a new Python using the shell. So, before the python code is executed, the env var is loaded. Ref: https://stackoverflow.com/questions/1178094/change-current-process-environments-ld-library-path But how to launch a sub-process that changes the environment parameter: You can ref: https://stackoverflow.

Get to know How deepwalk works by this project. Two steps: 1. gen the graph, and gen the corpus on the graph via random walk. 2. use the corpus generated by step1 to fit the Word2vec model and calculate the similarity of two nodes. Project link: https://gitee.com/sonica/basic-deepwalk Read more about develop word2vec model with python: https://machinelearningmastery.com/develop-word-embeddings-python-gensim/ This blog will tell you: How to train your own word2vec word embedding model on text data. How to visualize a trained word embedding model using Principal Component Analysis.

This is a tutorial of how to use *args and **kwargs For defining the default value of arguments that is not assigned in key words when calling the function: def func(**keywargs): if 'my_word' not in keywargs: word = 'default_msg' print(word) else: word = keywargs['my_word'] print(word) call this by: func() func(my_word='love') you’ll get: default_msg love read more about *args and **kwargs in python: https://www.digitalocean.com/community/tutorials/how-to-use-args-and-kwargs-in-python-3 Add more about default value if arg key is not assigned: def make_hastie_10_2(n_samples=12000, random_state=None): """Generates data for binary classification used in Hastie et al.

Graph Neural Networks for Computer Vision I was attracted by this image: This is an inspiring image and it was posted in this article: Tutorial on Graph Neural Networks for Computer Vision and Beyond (Part 1) written by Boris, a PhD student at University of Guelph. Link: https://medium.com/@BorisAKnyazev/tutorial-on-graph-neural-networks-for-computer-vision-and-beyond-part-1-3d9fada3b80d The figure I attached above is showing some possibilities that using the graph structure to represent the version components in a fuzzy way. That’s innovative and interesting.
