pip_smart_install

Automatically resolve version problem when using pip install -r requirements.txt

Smoothly install all dependencies in your requirements.txt even if pip cannot find the specified version (then the default version will be installed).

Usage:

cd /path/to/requirements.txt
git clone https://github.com/Tangent-H/pip_smart_install.git
conda activate <env_name> # enter conda environment if needed
python smart_install.py

Alternatively (even an easier approach):

1. cd the directory with a requirements.txt
2. conda activate <env> if needed
3. make sure there is no such a file named smart_install.py in this directory because the following command tried to remove this file after installing all the requirements

wget -nc https://raw.githubusercontent.com/Tangent-H/pip_smart_install/main/smart_install.py && python smart_install.py && rm smart_install.py

Example:

cd test
conda activate test
wget -nc https://raw.githubusercontent.com/Tangent-H/pip_smart_install/main/smart_install.py && python smart_install.py && rm smart_install.py

if the requirements.txt looks something like this:

# default installation
numpy
# wrong version
pillow==1.2.3.4
# correct version
matplotlib==3.8.0
# package not exist
NoSuchPackage

The output of the script looks something like this:

Running in a Conda environment located at: /home/tan/anaconda3/envs/test
Found requirements.txt.
Do you want to continue with the installation? [y/n]: y

# pip install standard output
