问题 When I import the function check_array from module sklearn.utils.validation , it got an Import Error ( ImportError: cannot import name check_array ). The tab completion got check_arrays , but I'm wondering there only exists a function called check_array in validation.py ( source code on Github). Besides, the spectral clustering algorithm implemented in scikit-learn/sklearn/cluster/spectral.py also used from ..utils.validation import check_array , not check_arrays . I'm quite confused about

问题 I am starting to get into python and yes, I have searched this site and the web for an answer, but somehow I really can't get it to run. I've created a spiderclass EbaySpider, residing in spider/ebay.py that I can start from the command line without problems (even with output to a JSON file). Now I want to start scrapy from within another .py file, so I can directly access the crawled data and output it to a GUI (will think about how to do that later). I have taken the code from this question

问题 I am trying to run this Python Program on Ubuntu but I am getting an error that says ImportError: No module named visual Can you guys please guide me on how can I resolve this issue? 回答1: visual module has been renamed to vpython lately.
