pychembldbis a Python interface for ChEMBLdbRequirementsPython 3.7 or later (not support 2.x)MySQL-python >= 1.2.4 or psycopg2 >= 2.5.1SQLAlchemy >= 1.3.1ChEMBLdb and Python versionpychembldb-0.1.x support chembl_14 and Python2.7pychembldb-0.2.x support chembl_15, 16 and Python2.7pychembldb-0.3.x support chembl_17,18,19 and Python2.7pychembldb-0.4.0 support chembl_25 and Python3.7SetupInstallpip install pychembldbor install from githubgit clone https://github.com/kzfm/pychembldb.git
cd pychembldb
sudo python setup.py install
or
pip install -e .Setting up engine_urlif you change engine_url, you should set CHEMBL_URI environment variable (default:mysql://root@localhost/chembl_25)ex) PostgreSQLexport CHEMBL_URI="postgresql+psycopg2://localhost/chembl_25"
