Welcome! Here are some setup tips to help get you started.
We have chosen to use a Jupyter notebook (previously iPython notebook), for its nice didactic, easy-reading style. You can find installation details here, or we provide our preferred installation method below.
You will want to have installed
python 3.6
jupyter
numpy
scipy
matplotlib
opencv
Visual Studio Code has very good debugging tools. You should have already created an environment from last week's lab with the instructions on moodle. Here they are again:
- Reboot the PC and select Windows (may not be essential, but if it works in Windows..)
- Download and install VS Code
- In VSCode, install the Python extension
- In VSCode, install the Jupyter extension
- Download and install MiniConda
- Open the Anaconda Prompt (AP) and use that to run commands you find in the "Conda Cheat Sheet" - just search for it online. --> Ok, so in the lab, you may lack permissions to update all the existing packages - should still be ok.
- AP: conda create --name MV00 --> you could also specify a specific Python version, instead of the newest, e.g. python=3.9.7. You should be using a Python version around 3.7 or newer for our labs.
- AP: conda activate MV00
- AP: conda install numpy (as an example of a package you must install, before you can import that package into your code, e.g. for Part C of today's lab)
- AP: conda install jupyter (you'll need this so that VS Code can operate on notebook files)
- Close and re-run VS Code so it sees your new environment
- In VS Code, open any .ipynb file. Then in the upper right corner, select the Python environment that you created earlier (e.g. MV00).
- Download anaconda: https://www.anaconda.com/download/
- Create a new environment:
conda create -n machinevision python=3.7
- Enter that environment:
source activate machinevision
- Download packages:
conda install jupyter numpy scipy matplotlib opencv
- Launch Jupyter:
jupyter notebook
If upon installation you read the error native kernel (python3) is not available
,
then try:
conda install ipykernel
python -m ipykernel install --user
