QUESTION
I'm trying to run my code in Python through Windows 10 cmd like this:
python3 flir_image_extractor.py -avg -i 'C:\\Users\\Daniel\\Desktop\\example.jpg'
The first thing it does is checking if the input path it's a file:

Answered 2021-May-20 at 19:44If you're on windows, do not enclose your command line arguments in single quotes, they are passed as literals to your application. Either use doube quotes, or - if your path does not contain spaces - don't use quotes at all.
You probably could have figured that out yourself if you'd print out the filename as part of the error message.
Also: single quotes will not prevent a command line argument from being split if it contains spaces.

I wrote a script to find spelling mistakes in SO questions' titles. I used it for about a month.This was working fine.
But now, when I try to run it, I am getting this.
...ANSWER
Answered 2017-Feb-24 at 15:05So apparently the default display number of questions per page is 50 so the range you defined in the loop goes out of the available number of pages with 50 questions per page. The range should be adapted to be within the number of total pages with 50 questions each.
This code will catch the 404 error which was the reason you got an error and ignore it just in case you go out of the range.

ANSWER
Answered 2018-Nov-26 at 17:02Objects in Python do not automatically support slice notation just because they support indexing. That has to be programmed in. There may be syntax more convenient than what you're using though.
If it's iterable, you can convert to a list first, and then slice it, like
QUESTION
I have build a store management system and had compiled it with pyinstaller like "pyinstaler -F admin1.py".
It has given me a build file and a dist file when I run the app on my computer it runs perfectly. I have copyed the dist folder to another computer but it does not run so I need to copy the build file to or is their an other way of copying the file to other systems. I am only using tkinter, os module and datetime modules but I have spited my program in different modulus.
...ANSWER
Answered 2018-Aug-24 at 19:57I can't comment, as I don't have enough reputation, but do you have any error messages from the other computer you're trying to run this batch file on?
According to this section of the pyinstaller documentation, you will need to send the recipient of your executable the "build" directory. This is because build contains all of the dependencies in your script. To quote the section about importing in one folder (NOTE: don't worry, I see the onefile option you set. This is just the section where the docs allude to the build directory you're inquiring about):
Another advantage of a one-folder bundle is that when you change your code, as long as it imports exactly the same set of dependencies, you could send out only the updated myscript executable. That is typically much smaller than the entire folder. (If you change the script so that it imports more or different dependencies, or if the dependencies are upgraded, you must redistribute the whole bundle.)
I think -F still creates a /build directory (so you can still track dependencies). Iwould share that out, as it would be shared with the one folder option as well. Pyinstaller knows to look for Tkinter (also in doc linked above), so at least you don't have to worry about that part. When you use onefile, the /dist directory should be empty, or at least it is when I create executables.
Try out the one folder method and send that folder out to whatever computers you need to. Let me know if this helps.
TLDR; Yes, share out the build file. It contains all of your dependencies. The dist file shouldn't contain anything for the "-F" option.

I'm trying to patch dependencies with my errbot tests. The problem I'm having is how errbot imports modules. It is not static and breaks my patch decorators as I add tests or they test in a different order.

Answered 2017-Oct-30 at 12:04My solution feels a bit hacky but it works. If anyone has a more elegant solution please share. I'll accept my own answer after awhile if there are no additional responses.
So I've come across this before but I guess I still wasn't familiar enough with how patching works in Python with knowing where to patch. After reading the "Where to patch" documentation ( again :) ) I have a work-around given the dynamic imports with errbot.
An errbot project folder will look something

Tested my pipeline on DirectRunner and everything's working good. Now I want to run it on DataflowRunner. It doesn't work. It fails even before enter my pipeline code, and I'm totally overwhelmed by the logs in stackdriver - just don't understand what they mean and really don't have any clue on what's wrong.
- execution graph looks loaded fine
- worker pool starts and 1 worker is trying to run through the setup process, however looks never success
some logs that I guess might provide useful information for debugging:

Answered 2017-Jun-15 at 17:12You seem to be using incompatible requirements in your REQUIRED_PACKAGES
directive, i.e. you specify "apache-beam==2.0.0"

, which conflict with each other. Can you try removing / uninstalling the "apache-beam"
package and install / include the "google-cloud-dataflow==2.0.0"
package instead?

Install pyed
You can use pyed 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.
