QUESTION
I have the following string which I need to split on space, commas, and next line character.
Sample string: "./homework2 3,phone3,desc3,brand4\n4,phone4,desc4,brand4\n5,phone5,desc5,brand5
"
I am using split function as: .split("[,\\s+\\n+]");
but I am unable to get the required out put. The program keeps reading brand4\n4
as one substring.
Help would be appreciated.

QUESTION
This is the error i get when I try to train my network.
The class we used to store Images from the Caltech 101 dataset was provided us by our teachers.
...ANSWER
Answered 2019-Dec-07 at 03:34The first dimension of the tensor means the color, so what your error means is that you are giving a grayscale picture (1 channel), while the data loader expects a RGB image (3 channels). You defined a pil_loader function that returns an image in RGB, but you are never using it.
So you have two options:
Work with the image in Grayscale instead of rgb, which is cheaper computationally speaking. Solution: Both in train and test transforms change
transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5))
fortransforms.Normalize((0.5), (0.5))
Make sure your image is in rgb. I don't know how your images are stored, but I guess you downloaded the dataset in grayscale. One thing you could try is using the pil_loader function you defines. Try changing
img = Image.open(os.path.join(self.root, self.elements[index].rstrip()))
forimg = pil_loader(os.path.join(self.root, self.elements[index].rstrip()))
in yout__getitem__
function.
Let me know how it goes!

Basics of assignment
- Use Visual Studio (I'm in 2019, thank you school!)
- Create console app that displays Magic 8 Ball style responses randomly to any text entered in line.
- This list is stored as a .txt file somewhere within the solution
- Create windows form app that allows a user to enter new responses that are saved to the list pulled in the console app above
- This only accepts one line at a time with a listbox displaying the results and a save button for saving. Form has label ("Enter a magic response!"), text box for input, list box for displaying list from .txt file, and save button to add text box entry to .txt file.
I don't know how to reference across projects, and my developer lingo is still too underdeveloped for me to conduct a worthwhile Google search. I simply don't know how to reference a relative path that keeps things contained. I only know how to reference an absolute path:
...ANSWER
Answered 2019-Sep-06 at 05:05You can use ..
to go up a directory relative to the current one. So going from C:\Windows\Temp
using ..\..\ProgramData
would get you to C:\ProgramData
.
The current dir is referenced with .\
for going downwards in the tree.
So using the previous example .\Temp1
would get you to C:\Windows\Temp\Temp1

I am trying to get user input for Yes or No (Y or N), but I keep running into complications. I also have to make it so that lowercase y and n work. I was wondering what the best way to go about this would be? Here is my program:

Answered 2018-Oct-13 at 20:59Right now the problem is that you cannot call .equals()
on a char
. Instead simply read from System.in
as a String
and use the method .equalsIgnoreCase()
so it will match either an upper case Y/N or lower case y/n:

I encountered this problem when I try to compile my code I thought it might be caused by header files including each other. But as far as I can tell I did not find any issues with my header files

...ANSWER
Answered 2018-Oct-15 at 14:47When you build your project, each .cpp file gets compiled separately into different object files. The once
in #pragma once
only applies to the compilation of a single .cpp file, not for the project as a whole. Thus if a .cpp file includes header A and header B, and header B also includes header A, then the second include of header A will be skipped.
However, if you have another .cpp file that includes A, A will be included in that object file again -- because #pragma once
only works when compiling a single .cpp file.
An #include statement literally takes the content of the included file and "pastes" it into the file that included it. You can try this by looking at the output of the C preprocessor tool (cpp
in the gcc
toolchain). If you are using the gcc toolchain, you can try something like this to see the file after its includes have been applied:

...ANSWER
Answered 2018-May-27 at 11:50It seems that intero
needs a package.yaml
and a stack.yaml
in order to locate your source files. You can just run stack init
or stack new
to auto matically generate these project files.
I met this problem several times. The above method solved my problem on my Windows and Fedora, so I hope this will help you.

Install homework2
You can use homework2 like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
