The versionnumber is displayed pretty obvious, still I can't get it because I don't know how to process java script properly. I tried parsing it out with requests_html from: <li>Version: <span data-code="PCP" data-release-version=""></span></li> This part should look like this after java script has done its job: <li

GUI - tkinter : how to access parameters of specific buttons?

问题 Like many other python beginners, I am playing around with GUIs (tkinter). For my little project, I wanted to create a grid of 5x5 buttons, that is 25 buttons in total, and interact with them: when you click on any of those 25 buttons, some buttons will change around the clicked button. I won't go into much details about what I want the final result to be, unless you think it is relevant. You will find bellow a code snippet that was adapted for this question in particular. The question, btw,

Gensim: Any chance to get word frequency in Word2Vec format?

旧时模样 提交于 2020-01-25 06:54:28
问题 I am doing my research with fasttext pre-trained model and I need word frequency to do further analysis. Does the .vec or .bin files provided on fasttext website contain the info of word frequency? if yes, how do I get? I am using load_word2vec_format to load the model tried using model.wv.vocab[word].count, which only gives you the word frequency rank not the original word frequency. 回答1: I don't believe those formats include any word frequency information. To the extent any pre-trained word

ERROR: Failed building wheel for mysqlclient

问题 I'm unable to 'pip install mysqlclient', and every attempt returns the error: 'ERROR: Failed building wheel for mysqlclient'. For context, I'm running on macOS Mojave 10.14.5. The rest of this post assumes that both 'python==3.6' and 'virtualenv' are already downloaded. In addition, x-code command line tools are already installed (not that I think that matters). The steps to this are (from command line): 'virtualenv ~/venv' Output: Using base prefix '/usr/local/Cellar/python/3.6.5_1
