#RaspberryPi – 6 commands to install #OpenCV for #Python in #RaspberryPi4

Hi !

Quick post to remind me the 6 commands to install OpenCV in my Raspberry Pi

sudo apt-get install libhdf5-dev libhdf5-serial-dev libhdf5-100 
sudo apt-get install libqtgui4 libqtwebkit4 libqt4-test
sudo apt-get install libatlas-base-dev
sudo apt-get install libjasper-dev
wget https://bootstrap.pypa.io/get-pip.py
sudo python3 get-pip.py
sudo pip3 install opencv-contrib-python

There is an optional command to update pip, which is always nice.

Happy Coding!

#Python – Can’t install TensorFlow on Anaconda, maybe is the Visual Studio distribution

Hi!

This is the 2nd time I get a weird error when I install TensorFlow in my Anaconda distribution. And this is the 2nd time I realize that I’m using the Anaconda version that is preinstalled with Visual Studio. I’m not sure if the spaces in the path affects the creation of environments or it’s something else, however my current and big and amazing solution is:

  • Uninstall Anaconda
  • Install Anaconda again

And then, follow the simple commands in the official Anaconda and TensorFlow doc (see references)

conda create -n tensorflow_env tensorflow
conda activate tensorflow_env

Once tensorflow is installed, I usually test this in python

> Python 
import tensorflow as tf
print(tf.__version__)

Note: please ignore the typos!

anaconda start python and test anaconda version

Now TensorFlow is installed and it’s time to move forward with a new development environment.

Happy Coding!
