Initial Setup

Conda + Dependencies installation

Conda is a package/dependency management system for python.

We will use the miniforge installer and install it through pyenv.

1. Install Homebrew

If you don't have homebrew already install it over here: https://brew.sh/

2. Install pyenv

Run:

brew install pyenv

3. Install miniforge

Run:

pyenv install miniforge3-4.10.3-10
pyenv global miniforge3-4.10.3-10

4. Create conda environment

Navigate to the projects root directory.

Run:

conda create --name env_embedded python=3.8
conda activate env_embedded

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate': To fix run conda init zsh (replace zsh with whatever shell you are using if not zsh)

5. Adding dependencies

5.1. Install tensorflow

The required version of tensorflow is 2.6.0

Intel Installation

pip install tensorflow==2.6.0

M1 Installation

conda install -c apple tensorflow-deps==2.6.0
pip install tensorflow-macos==2.6.0
pip install tensorflow-metal==0.2.0

5.2. Install numpy

conda uninstall numpy && conda install numpy=1.19.2

clang: error: the clang compiler does not support 'faltivec'. To fix run: brew install openblas && OPENBLAS="$(brew --prefix openblas)" conda install numpy

ERROR: Failed building wheel for h5py. To fix run conda install h5py

5.3. Install pytorch + pycoco

conda install -c pytorch torchvision
conda install -c conda-forge pycocotools

5.4. Install imgaug

pip install imgaug

Error: tensorflow-macos 2.6.0 requires numpy~=1.19.2, but you have numpy 1.24.1 which is incompatible. Make sure previous version of numpy is uninstalled.

5.5. Instal pyqt5

This will take a long time... (>20 mins)

pip install pyqt5 --config-settings --confirm-license= --verbose

AttributeError: module 'sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel'. Need to install qt5 via brew, then add to path: https://stackoverflow.com/questions/65447314/attributeerror-module-sipbuild-api-has-no-attribute-prepare-metadata-for-bui/67606704#67606704

5.6. Install pixellib

pip install pixellib

5.7. Install jupyter

conda install jupyter

6. Install models

cd scripts
chmod +x ./getModels.sh
./getModels.sh
