问题 I have to simulate a liquid flow through a square matrix that contains a set of integers. The liquid should start from the top left corner of the matrix. It could only move towards right or below adjacent matrix. The lower value of the adjacent matrix, the higher potential for it to flow. The movement of the liquid is considered stop at the right or below edge of the matrix. The program should be able to show the sum of all numbers that the liquid has passed through. import numpy as np mtr=

问题 I am trying to set up crontab for a script written in python which is intalled via Anaconda. The simple .py runs (it just loads a module for a demo) and can be run in terminal with python a.py . The problem is getting crontab the path for python and imported modules. I have been trying to set the PATH and PYTHONPATh to the python directory and also where pandas is located. I think this is a env issue but have no idea what that means. Any ideas? The crontab is: SHELL=/bin/sh PYTHONPATH=/Users

问题 Is there away to use variables and string together? For example I would like to, define my path's and other options combining variables and string? #Add Directory - name: Add Directory win_file: path: "{{directory_path}}\AppName-{{env}}" state: directory #Add IUSR to directory path - name: ADD IUSR win_acl: path: "{{directory_path}}\AppName-{{env}}" user: IUSR rights: Read type: allow state: present propagation: 'NoPropagateInherit' #Add website - name: "{{env}} Add App Name" win_iis_website:

问题 I have a new numpy version under /opt/lib/python2.7/site-packages , and a standard (system) version under /usr/lib/python2.7/dist-packages . I want to temporarily use the new numpy version so I add the following at the beginning of my script: In [1]: import sys In [2]: sys.path.insert(1,'/opt/numpy/lib/python2.7/site-packages') In [3]: sys.path Out[3]: ['', '/opt/numpy/lib/python2.7/site-packages', '/usr/local/bin', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7', '/usr/lib/python2.7

问题 Pytesseract is not recognized. I have tried all fixes documented online, including adding Tesseract-OCR to my Path variables, incorporating the pytesseract.pytesseract.tesseract_cmd = r'C:\Program Files\Tesseract-OCR\tesseract.exe' command path in my script, uninstalling and reinstalling pytesseract and tesseract. 回答1: In the line 23 vpnbookpassword = pytesseract.image_to_string(pwdi) there you have mentioned pytesseract.image_to_string but you have imported image_to_string from pytesseract

问题 The problem is as follow: Given an oriented weighted graph, a start node, an end node and a number k, verify if exist a path from the start node to the end node with at least length k. This is the code i wrote and it's correct but only in specific graph. For example g1 with weights1 is as follows: let weights1 = [(2,1,1);(2,1,3);(2,1,4);(1,1,5);(5,1,2);(5,1,6);(3,1,6);(6,1,7);(4,1,3)];; let f1 = function 1 -> [5] | 2 -> [1;3;4] | 3 -> [6] | 4 -> [3] | 5 -> [2;6] | 6 -> [7] | _ -> [];; type 'a

问题 In UNIX, i am trying to modify the LD_LIBRARY_PATH to make it include some libraries i can't add to the regular libraries of the system( I don't have root permission it's a university server...), at this point I have used many ways that I came across the web to do this but could not modify it neither can i see what is the PATH .. I have tried using: LD_LIBRARY_PATH="path-to-lib" but got :command not found. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path-to-lib but got: bad modifier in $ (/)

问题 I wanted to make a tree from an existing directory, so that it shows all of the subfolders and files inside. I did it with this code: File file = new File(path); TreeModel model = new FileTreeModel(file); JTree tree = new JTree(model); But now it shows the full path instead of just the folder/file name. If you don't know what I mean, this might help: Please help... I wanted to find the solution online but I didn't know how to describe the problem. :/ 回答1: import java.io.File; import java.util
