Description

We need to understand the ODM software's capabilities:

  • use a virtual machine (set up with Windows' Hyper-V on one of the CAD machines)
  • use pictures taken by Chennai's drone surveyor in Feb. 2019 (reference?)

This ticket involves exploring the software, before eventually using using it in production, which would require a more solid process established after this experience

History

#1 Updated by Philippe May about 5 years ago

Quite few steps have been done so far, not documented in details, unfortunately.

Summary:

  • installed a Debian Stretch VM on Hyper-V: IP: 192.168.1.31, name (set in local DNS): odm1.csr.av
  • installed (on root account of that VM, quick and dirty but hey it's a VM accessible only locally) ODM from github, in /root/OpenDroneMap
  • setup ODM, which has quite a few dependencies: not too easy, not too difficult. Mostly, using packages from Debian when available, otherwise with Python/pip
  • setup project_path in settings.yml to /usr/local/odm

So far, the installation seems to be successful:

cd /root/OpenDroneMap
./run.sh TestProject1

Next steps:

  • Install WebODM
  • Setup a share with Windows to access the images

#2 Updated by Philippe May about 5 years ago

Installing WebODM:

Install Debian packages (~ found in requirements.txt and trying to launch the web server):

apt install python3-venv nginx redis-server celeryd grass

Create a virtual environment (should have done it for ODM, will redo probably later on):

cd ~/WebODM
python3 -m venv /usr/local/venv/webodm
pip install -r requirements.txt 

#3 Updated by Philippe May about 5 years ago

Requires a postgis server, let's install it locally as i don't want to touch our DB server in this phase:

apt install postgis

Create a superuser (yark):

su - postgres
createuser -s -P webodm

Configure webodm/settings.py to use this connection.

Try to start the server:

./start.sh

The script has populated the database, run nginx as a process (bad: doesn't play well with the system).

Next, it wants node and npm. Let's try as found on https://linuxhint.com/install_npm_debian/.

OK (after temporarily deactivating the Aurinoco apt cacher config), npm is installed.

Running ./start.sh again, the node packages are fetched and should be able to be build.

Next episode tomorrow as now is mullu time :)

#4 Updated by Philippe May about 5 years ago

Just before going:

FileNotFoundError: [Errno 2] No such file or directory: 'webpack-cli'

#5 Updated by Philippe May about 5 years ago

Installed webpack and webpack-cli:

npm install -g webpack webpack-cli

Then (in WebODM base dir):

npm install

Then:

webpack

Launch the application (nginx frontend started by the ./start.sh script: nginx -c /root/WebODM/nginx/nginx.conf):

cd /root/WebODM
gunicorn webodm.wsgi --bind unix:/tmp/gunicorn.sock --timeout 300000 --max-requests 250 --preload

Check at http://odm1.csr.av:8000 : server running, but static files aren't served properly.

#6 Updated by Philippe May about 5 years ago

Next step: configure the nginx frontend correctly.

#7 Updated by Philippe May about 5 years ago

Installed config with standard nginx location (/etc/nginx). Tweaked quick and dirty permissions for the /root/WebODM directory: http://odm1.csr.av:8000 works as expected.

Created an account "admin" with a password.

WebODM asks for "Add processing node" with hostname, port and token, so ODM needs to be run as a service.

#8 Updated by Philippe May about 5 years ago

  • Assignee changed from Philippe May to Giulio Di Anastasio

Apparently, we also need nodeodm: https://www.opendronemap.org/nodeodm/

1) Install PotreeConverter and LASzip dependency

mkdir /usr/local/staging
git clone https://github.com/pierotofy/LAStools /usr/local/staging/LAStools
cd /usr/local/staging/LAStools/LASzip
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make

git clone https://github.com/pierotofy/PotreeConverter /usr/local/staging/PotreeConverter
cd /usr/local/staging/PotreeConverter
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DLASZIP_INCLUDE_DIRS=/usr/local/staging/LAStools/LASzip/dll -DLASZIP_LIBRARY=/usr/local/staging/LAStools/LASzip/build/src/liblaszip.a ..
make && sudo make install

2) Install gdal2tiles.py script, node.js and npm dependencies

cd /usr/local/
git clone https://github.com/OpenDroneMap/NodeODM
cd NodeODM
npm install

3) Start NodeODM

cd /usr/local/NodeODM
node index.js --odm_path=/root/OpenDroneMap
info: Authentication using NoTokenRequired
info: No tasks dump found
info: Checking for orphaned directories to be removed...
info: Server has started on port 3000

Could add the node in the admin.

I created a user "giulio" with superuser rights, so one should be able to start exploring ODM and WebODM at http://odm1.csr.av:8000

Quite some work to be done to probably fix, and rationalize later the installation: please consider it to be a playground only, and start filling tickets...

  • There's a (required) component called "NodeODM" which i haven't set up to start automatically when the VM starts.
    To start it: see point 3 just above
  • Need also to start a gunicorn process: see comment #5

#9 Updated by Philippe May about 5 years ago

An idea for later, since the architecture of ODM, nodeODM and WebODM would allow to have a distributed computing environment.

I'm thinking of: WebODM running on a VM of our main server, and "computing nodes" in VMs across our network (hyper-V on Windows, etc).

#10 Updated by Philippe May almost 5 years ago

Created systemd services (in /etc/systemd/system) for:

WebODM OK.

The node service errors, and manually we're getting an error:

(webodm) root@odm1:/usr/local/NodeODM# /usr/bin/node index.js --odm_path=/root/OpenDroneMap
error: Error during startup: Could not load list of options from OpenDroneMap. Is OpenDroneMap installed in /root/OpenDroneMap? Make sure that OpenDroneMap is installed and that --odm_path is set properly: Unexpected token F in JSON at position 2

Will follow up later.

#11 Updated by Philippe May almost 5 years ago

  • Assignee changed from Giulio Di Anastasio to Philippe May

Added nodeODM service, with a config file /etc/nodeODM.json.

Web site seems OK, node is shown, but the test task doesn't start.

#12 Updated by Philippe May almost 5 years ago

Giulio tried another task and got a misleading error message, like 'only jpg can be added', but the files are actually jpg

#13 Updated by Philippe May almost 5 years ago

Most probably a bad error message, related to https://github.com/OpenDroneMap/WebODM/issues/615

In the journal log, got this error:

Mar 23 12:59:02 odm1 gunicorn[136464]: PermissionError: [Errno 13] Permission denied: '/root/WebODM/app/media/project/4'

So, better than tweaking permissions, let's spend a bit of time configuring the web server properly.

#14 Updated by Philippe May almost 5 years ago

It will takes more time to understand how webODM can be properly configured, so another quick and dirty trick:

chown -R www-data: /root/WebODM/app/media/project/

Also, found in node's logs (/var/log/nodeODM/node-OpenDroneMap.log):

2019-03-23T10:30:00.005Z - error: Could not dump tasks: EACCES: permission denied, open 'data/tasks.json'

Yet another quick and dirty trick:

root@odm1:# chown -R www-data: /usr/local/nodeODM/data/tasks.json

#15 Updated by Philippe May almost 5 years ago

One can access a web interface for odm-node, eg. at http://odm1.csr.av:3000

So i tried to create a task there, uploading one file, and after changing again some ownership to www-data (/usr/local/nodeODM/[tmp|data]), i could start the processing.

It failed with the error:

File "/root/OpenDroneMap/scripts/dataset.py", line 16, in make_odm_photo
force_ccd)
File "/root/OpenDroneMap/opendm/types.py", line 35, in __init__

File "/root/OpenDroneMap/opendm/system.py", line 15, in get_ccd_widths
with open(context.ccd_widths_path) as f:
IOError: [Errno 2] No such file or directory: '/root/OpenDroneMap/SuperBuild/src/opensfm/opensfm/data/sensor_data.json'

Enough for today, my mind is too full of errors. Will continue next week.

#16 Updated by Philippe May almost 5 years ago

Quick and dirty fix for openSFM, which was installed with normal pip and ODM isn't a nice player because it assumes the packages are installed to its predefined location:

root@odm1:~/OpenDroneMap/SuperBuild/src/opensfm# ln -s /usr/local/lib/python2.7/dist-packages/opensfm-0.4.1a7-py2.7.egg/opensfm .

For the opensfm script (hardcoded in /root/OpenDroneMap/opendm/system.py, why do they execute it as subprocess when it's a pyhton module??):

ln -s /usr/local/lib/python2.7/dist-packages/opensfm-0.4.1a7-py2.7.egg/EGG-INFO/scripts /root/OpenDroneMap/SuperBuild/src/opensfm/bin

#17 Updated by Philippe May almost 5 years ago

Next error:

ImportError: No module named pyopengv

Building from source:

cd /root
mkdir libs
git clone --recursive https://github.com/laurentkneip/opengv.git  # Recursive is for python/pybind11
cd opengv
cmake -D BUILD_PYTHON=ON .  # This was actually done using ccmake (ncurses interface for cmake)
make
make install

Installed in standard location (/usr/local/lib/, /usr/local/include/opengv), so probably need to be installed in /root/OpenDroneMap. But now, mullu time.

#18 Updated by Philippe May almost 5 years ago

For opengv: added in /etc/systemd/system/odm-node.service:

Environment=PYTHONPATH=/usr/local/lib/python2.7/dist-packages

Also, changed log file locations of both services (odm-gunicorn and odm-node) to /var/log/openDroneMap

Found that the node service executes python through a shell script, in /var/log/openDroneMap/node-OpenDroneMap.log:

2019-04-03T06:27:42.578Z - info: About to run: /root/OpenDroneMap/run.sh --project-path /usr/local/nodeODM/data d1837535-25b2-4cb3-8e15-e236f93a9a03

Let's see:

www-data@odm1:/root/OpenDroneMap/opendm$ cat /root/OpenDroneMap/run.sh
#!/bin/bash

RUNPATH="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" 
export PYTHONPATH=$RUNPATH/SuperBuild/install/lib/python2.7/dist-packages:$RUNPATH/SuperBuild/src/opensfm:$PYTHONPATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$RUNPATH/SuperBuild/install/lib
python $RUNPATH/run.py "$@" 

So, that script tells us that python modules run by node is probably expected in the (messy) ODM installation in that SuperBuild directory, but the python executable is set by the environment. Ideally, it should be in a venv.

#19 Updated by Philippe May almost 5 years ago

Some progress: after installing (correctly?) pyopengv, it's available:

www-data@odm1:~$ python -c 'import pyopengv' && echo OK
OK

I think it's moving on, as WebODM now displays quickly some activity when but WebODM is still stuck with "Resizing images..."

Trying to run manually gives some clue:

Improve the installation by pulling WebODM settings out of git code base:

#22 Updated by Philippe May almost 5 years ago

Next error:

[Errno 13] Permission denied: '/root/WebODM/plugins/contours/public/webpack.config.js'

The git pull above created this new plugin.

Fix (another bad practice to give write permissions to the www-data user, again):

chgrp -R www-data /root/WebODM
chmod -R g+w /root/WebODM

#23 Updated by Philippe May almost 5 years ago

Quick note in-between, for using the virtual env for WebODM:

su - www-data -s /bin/bash
. /usr/local/venv/webodm/bin/activate

#24 Updated by Philippe May almost 5 years ago

Next: found in WebODM/README.md that i missed a component: celery.

To start it (in the python virtual env):

celery -A worker worker --autoscale $(grep -c '^processor' /proc/cpuinfo),2 --max-tasks-per-child 1000 --loglevel=warn

Error is: password authentication failed for user "postgres" => need to configure it to use Django's settings.

=> created the odm-celery.service, so should be enabled/started automatically.

#25 Updated by Philippe May almost 5 years ago

Some visible progress: now, we see "running" in the tasks (Dashboard page) so the step "Image Resize / Upload" is passed. But, nothing moves after that.

#26 Updated by Philippe May almost 5 years ago

Got a bit more clarity (from https://github.com/OpenDroneMap/WebODM#architecture-overview):

We use Celery workers to do background tasks such as resizing images and processing task results, but we use an ad-hoc scheduling mechanism to communicate with NodeODM (which processes the orthophotos, 3D models, etc.). The choice to use two separate systems for task scheduling is due to the flexibility that an ad-hoc mechanism gives us for certain operations (capture task output, persistent data and ability to restart tasks mid-way, communication via REST calls, etc.).

So, celery and node are 2 different and required "workers", celery runs first in the workflow, then only node. I wish that it would be more clear, as, eg. WebODM/worker.sh deals with celery only.

In practice, this seems to unlock the pending tasks:

(webodm) www-data@odm1:/root/WebODM$ ./worker.sh start

I don't understand why the main WebODM start script launches ./worker.sh scheduler start.

So, it's just a matter starting correctly that celery worker from systemd to get this right.

#27 Updated by Philippe May almost 5 years ago

  • Tracker changed from Bug to Support

Finally, i'm giving a try with docker:

  • installed docker in debian, with docker apt repo
  • created user phil with sudo group

Run:

cd /usr/local/WebODM ; docker-compose up
phil@odm1:/usr/local$ docker run -p 3000:3000 opendronemap/node-opendronemap
  • Open web interface at port 8000 => OK
  • Register node with hostname: odm1.csr.av:3000
  • Create task with few images: opensfm seems to be OK.

4GB RAM wasn't enough (cache hit): gave 16GB, rebooted the VM. Processing, will see after a while.

#28 Updated by Philippe May almost 5 years ago

I still don't really understand how to manage the docker images, and specifically to have them started at boot time. Currently, it seems that the node is started, but the webapp isn't. So, after start of the VM, one needs to:

cd /usr/local/WebODM ; docker-compose up

#29 Updated by Philippe May almost 5 years ago

For the second time, the disk of the VM was filled with docker "overlay" (/var/lib/docker/overlay2: 42GB). Even no space left at all on device for the docker to start.

The first time, i have run "docker system prune", which freed all that space but got to recreate the docker image, with possible data loss (?).

Doesn't work now:

root@odm1:/usr/local/WebODM# docker system prune -f
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Of course it cannot run because that damn stupid thing filled up the whole filesystem, the machine was rebooted and it cannot start anymore.

Enough for today.
