问题 I am fairly new to python and the only SQL I know is from this project so forgive the lack of technical knowledge: def importFolder(self): user = getuser() filename = askopenfilename(title = "Choose an image from the folder to import", initialdir='C:/Users/%s' % user) for i in range (0,len(filename) - 1): if filename[-i] == "/": folderLocation = filename[:len(filename) - i] break cnxn = pyodbc.connect('DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\Users\Public

问题 I am trying to run Ruby On Rails, but every time I start it (even if I run rails without arguments, when it should display some help) it produces an error: serge1peshcoff@myLaptop:~$ rails /home/serge1peshcoff/.rvm/rubies/ruby-2.2.3/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': /home/serge1peshcoff/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/x86_64-linux/digest/md5.so: undefined symbol: rb_Digest_MD5_Init - /home/serge1peshcoff/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0

问题 I am getting this error when I am trying to remove an item from an arraylist after it collides with something else. Below is my AsyncTask and the logcat error that goes with it. Does anyone see where I am going wrong? Here is my AsyncTask: public class handleCollisions extends AsyncTask<String, Integer, String> { @Override protected String doInBackground(String... arg0) { Enemy tempE; for(int i = 0; i < enemies.size(); i++) { tempE = enemies.get(i); playerR = new Rect((int)x, (int)y, (int)x +

问题 Sorry if this is a total newbie question, but I am not sure how to solve this problem. I'm currently getting these errors when I try to run the code below: bot.rb:58:in `rescue in initialize': Can't load bot data (RunTimeError) bot.rb:55:in `initialize' basic_client.rb:3:in `new' basic_client.rb:3:in `<top (required)>' Here is the source code for bot.rb, and the error appears to be at the "@data = YAML.load(File.open(options[:data_file]).read)" part. # A basic implementation of a chatterbot

问题 I can't seem to get past this and do not quite understand what is happening. I have a directory with two class files in it. Using the REPL from within that directory I can import both files and execute their logic. From their parent directory which main() is ran from however, only one class file is visible, pagetable. The project structure is currently, project/ src/ __init__.py # empty pagingsimulation.py # main() imports memory process.py memory/ __init__.py # imports pagetable.py pagetable

问题 My app renders 3D models via opengl ES2, once at a time. When I enable textures in those model my app crashes. First, I thought that was because the texture images are large, but the truth is that they are not. For instance, in one of the models, I use four .png images of sizes 4kb, 38kb, 39kb, and 200kb respectively. Are they large? I don't think so, but reading the logcat it seems that everything comes from a memory problem: 08-26 02:08:13.574: I/art(10870): Background sticky concurrent

问题 I Have been working on a small app, which can calculate complex numbers for me (division, subtraction, multiplying etc.). I have no apparent compile errors, but when i run the program I get a bunch of run-time errors which I can't understand or know how to fix. Am i missing something obvious?
