Extend contributing.md about cvat HOT 8 CLOSED

Good idea,
I will prepare step by step manual at near time.

from cvat.

So, I have tried next steps on clean Ubuntu 18.04. You need:

• Install some dependencies and applications:

sudo apt-get install curl redis-server python3-dev python3-pip python3-venv libldap2-dev libsasl2-dev -y

• Install Visual Studio Code for development

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list'
sudo apt-get install code -y

• Perform CVAT installation steps

git clone https://github.com/opencv/cvat
cd cvat && mkdir logs keys .vscode
python3 -m venv .env
. .env/bin/activate
pip install --upgrade wheel
pip install -r cvat/requirements/development.txt 
python manage.py migrate
python manage.py collectstatic

• Put launch.json (launch.zip) to cvat/.vscode dir

• Create super user and run Visual Studio Code from virtual environment

python manage.py createsuperuser
code

In visual studio code:

1. Go to extensions and install "Debugger for Chrome" (also you can debug it directly in the browser . It more convenience for me) and Python. Reload.
2. Open cvat dir (Ctrl+O and open), select "CVAT Debugging" configuration and press F5.
3. You are great!

We will update contributing.md in near future.

I had some problems following the instructions; I could fix the first 2, but got stuck on the third. You might want to update the instructions related to the first 2 issues. Hopefully someone can help me over the 3rd one.

OS: Ubuntu 19.04

1. When I ran the following commands:
   pip install -r cvat/requirements/development.txt`
   I got a lot of errors related to installing Pillow:

`writing manifest file 'src/Pillow.egg-info/SOURCES.txt'
running build_ext

The headers or library files could not be found for zlib,
a required dependency when compiling Pillow from source.

Please see the install instructions at:
https://pillow.readthedocs.io/en/latest/installation.html

Following the instructions here helped:
sudo apt install libjpeg8-dev zlib1g-dev

2. Running "cvat.js debug" in Visual Code gave me:
   "cannot find runtime node on PATH. Make sure to have node installed"

Installing node and npm helped.

3. Running "cvat.js debug" in Visual Code now gives me:

/usr/bin/node --nolazy --inspect-brk=9230 src/api.js
Debugger listening on ws://127.0.0.1:9230/d24de8ef-920f-4bd3-9a6f-72c1f65532d9

Any ideas?

PS. cvat/.vscode/launch.json file already existed in Git, this step is unnecessary.

Hi @raunilillemets , we cannot support different OS for development. At the moment internally all engineers are using Ubuntu 18.04 (LTS). If you want to use Ubuntu 19.04 it is necessary to investigate on your own.

@bsekachev , could you please help with cvat.js?

from cvat.

@raunilillemets
Before you can debug cvat-core.js you need to install all node.js dependencies.
cd cvat-core && npm install

from cvat.

Thanks @bsekachev.

Well, some of things which I mentioned are likely also relevant on Ubuntu 18.04.
For example, the first issue seems to affect different versions of Ubuntu, as mentioned here.

Anyway, after running npm install in cvat-core, debugging the application now gives me the following error:

Error: No such module: http_parser

Any clues?

@raunilillemets
Try this

from cvat.

The suggestions there did not help, still had the same issues.

But I noticed that there are 2 really similar profiles:
"cvat.js debug (cvat)"
"debugging (cvat)"

I was using the first one and getting errors; I tried the second one and it seems to work (at least I got into the login page). I will continue using the second one.
