I've forked dlandon's Zoneminder project in order to build a Docker image using Debian Bullseye instead of Ubuntu, for i386 (I'm installing it into a 32-bit mini PC).
Part of the requiriments is installing dlib (latest is 19.22.0). I've installed the required dependencies (python3-pip, python3-setuptools and python3-wheel, as well as GCC and CMake).
When installing dlib, the terminal outputs:
Collecting dlib
Downloading dlib-19.22.0.tar.gz (7.4 MB)
Using legacy 'setup.py install' for dlib, since package 'wheel' is not installed.
Installing collected packages: dlib
Running setup.py install for dlib: started
...
The relevant part is (even with python3-wheel installed)
Using legacy 'setup.py install' for dlib, since package 'wheel' is not installed.
dlib builts successfully but takes a looong time to build, however. This happens with any packages supossed to use wheel.
I haven't found any (answered) questions about this specific issue, so, if there is something I missed, I would be told about that.
Everything is in the Dockerfile.
try pip install wheel in your env

I installed opencv-python and opencv-python-contrib
after i installed them I realized I wasn't supposed to
How do I uninstall it
Also, which one should I keep, to do facial recongnition with raspberry pi
Import cv2 didn't work when I tried to run a python file, I don't know why it is happening!
If you are using armbian or raspbian, you can uninstall packages with apt:
apt uninstall opencv-python opencv-python-contrib
I suggest that if you want to completely uninstall and remove configuration files use purge:
apt purge opencv-python opencv-python-contrib
and aftter that, you can uninstall packages that came with opencv:
apt autoremove --purge
If you need Extra modules: just keep opencv-python-contrib
Extra modules https://docs.opencv.org/4.x/index.html
pypi.org https://pypi.org/project/opencv-contrib-python/
Installation and Usage
If you have previous/other manually installed (= not installed via pip) version of OpenCV installed (e.g. cv2 module in the root of Python's site-packages), remove it before installation to avoid conflicts.
Make sure that your pip version is up-to-date (19.3 is the minimum supported version): pip install --upgrade pip. Check version with pip -V. For example Linux distributions ship usually with very old pip versions which cause a lot of unexpected problems especially with the manylinux format.
Select the correct package for your environment:
There are four different packages (see options 1, 2, 3 and 4 below) and you should SELECT ONLY ONE OF THEM. Do not install multiple different packages in the same environment. There is no plugin architecture: all the packages use the same namespace (cv2). If you installed multiple different packages in the same environment, uninstall them all with pip uninstall and reinstall only one package.
a. Packages for standard desktop environments (Windows, macOS, almost any GNU/Linux distribution)
Option 1 - Main modules package: pip install opencv-python
Option 2 - Full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python (check contrib/extra modules listing from OpenCV documentation)
b. Packages for server (headless) environments (such as Docker, cloud environments etc.), no GUI library dependencies
These packages are smaller than the two other packages above because they do not contain any GUI functionality (not compiled with Qt / other GUI components). This means that the packages avoid a heavy dependency chain to X11 libraries and you will have for example smaller Docker images as a result. You should always use these packages if you do not use cv2.imshow et al. or you are using some other package (such as PyQt) than OpenCV to create your GUI.
Option 3 - Headless main modules package: pip install opencv-python-headless
Option 4 - Headless full package (contains both main modules and contrib/extra modules): pip install opencv-contrib-python-headless (check contrib/extra modules listing from OpenCV documentation)
Im trying to install dlib for few cv2 projects, but I have problems installing it.I made everything without problem but when I wanted to finally do the python setup.py install It showed me this error message: Could NOT find Boost (missing: python) (found suitable version "1.79.0", minimum required is "1.41.0")
I mean why doesnt it work when it sees my installed Boost 1.79...
Does somebody know how to fix it guys?
Thank you anyways:)
From error log it looks like boost libraries are found, but it's missing specific boost library to integrate with python
You have not mentioned which OS you are using for debian & it's derivatives
sudo apt-get install libboost-python-dev or if you are installing specific version of boost sudo apt-get install libboost-python1.79-dev should install the python module.
If boost is built from sources, during bootstrapping enable python libs to be built
./bootstrap.sh --with-libraries=python,filesystem,serialization
for list of boost libs can be built
./bootstrap.sh --show-libraries
I tried following this guide to install ROS, but even after adding ROS source.list and its key
sudo apt install ros-melodic-desktop-full
gave error.
E: Unable to locate package ros-melodic-desktop-full
Then I ran this command
sudo apt search ros
to see if any such package exists. I couldn't find ros-melodic-desktop-full but I found another similar package ros-desktop-full.
So I installed it instead. The installation went smooth without giving any errors.
Next step in the guide is to set-up ROS environment variable, but I have no such directory
/opt/ros
So how do I setup the environment variable?
P.S.
I also installed some tools and dependencies with this command
sudo apt install python3-rosdep python3-rosinstall python3-rosinstall-generator python3-wstool build-essential
and initialized rosdep
sudo rosdep init
rosdep update
The ros-desktop-full package you installed is part of the official Ubuntu release.
ROS Melodic (and in the future, Noetic) is published by the OSRF in a separate repository (packages.ros.org). These packages install to /opt/ros/. However, some ROS packages have also been ported to Debian, which is how they found their way to Ubuntu (which derives from Debian).
The Debian packages are fully functional, but they do not install to /opt/ros. Instead, everything is integrated in the operating system itself. This means that you need to set up your personal workspace slightly differently.
Given that most tutorials assume that you use the OSRF packages, I suggest you either wait for the Noetic release (scheduled for the end of May 2020), then install ros-noetic-desktop-full, or downgrade to Ubuntu 18.04 LTS to use ROS Melodic.
From the documentation here, melodic is only supported on Ubuntu 18.04. The ROS version targeting Focal (20.04) is Noetic, but that one has not been released yet (see Distributions). I'm not sure what ROS version Ubuntu packages (the ros-desktop-full one you installed), but I was not successful in using it.
If you really do want to use Ubuntu 20.04, then I think your best option currently is to compile from source. Last time I checked the precompiled debs for Noetic are not yet available at http://packages.ros.org/ros/ubuntu (you can track release progress at github issue 21513). No idea if compiling Noetic from source is easy or hard, but I was able to compile ROS2 foxy from source without too much trouble though.
I need to install a Tensorflow nightly build since the latest stable release has a critical issue that doesn't allow me to work that seems fixed in nightly.
I want to avoid to try to compile myself Tensorflow from source and I have found a guide about installing Nightly build using PIP
Eg this command
pip install http://ci.tensorflow.org/view/Nightly/job/nightly-matrix-cpu/TF_BUILD_IS_OPT=OPT,TF_BUILD_IS_PIP=PIP,TF_BUILD_PYTHON_VERSION=PYTHON3,label=mac-slave/lastSuccessfulBuild/artifact/pip_test/whl/tensorflow-0.11.0rc1-py3-none-any.whl
was for tensorflow 0.11 nightly build for Mac
Looking at this link and link for windows nightly build:
I have tried to adjust the command to install tensorflow 1.0.1 for windows nightly in this way:
pip install http://ci.tensorflow.org/view/Nightly/job/nightly-win/TF_BUILD_CONTAINER_TYPE=CPU,TF_BUILD_IS_OPT=OPT,TF_BUILD_IS_PIP=PIP,TF_BUILD_PYTHON_VERSION=PYTHON3 /lastSuccessfulBuild/artifact/pip_test/whl/tensorflow-1.0.1-cp35-cp35m-win_amd64.whl
with no success
Could someone help me?
I downloaded the latest Nightly Build from Jenkins (https://ci.tensorflow.org/view/Nightly/job/nightly-win/DEVICE=cpu,OS=windows/121/)
I put the file in C:\tensorflow\tensorflow-1.0.1-cp35-cp35m-win_amd64.whl
And was able to successfully install with
pip3 install C:\tensorflow\tensorflow-1.0.1-cp35-cp35m-win_a
md64.whl
