I installed the library and when trying to access SQL in jupyter notebook with my credentials the following error appears:
DatabaseError: DPI-1047: Cannot locate a 64-bit Oracle Client library: "The specified module could not be found". See https://oracle.github.io/odpi/doc/installation.html#windows for help

Probably you have installed cx_Oracle Python library. In order to execute the DB connectivity through jupyter notebook, you need to install the Oracle Client and that is what missing in your scenario. Please follow the steps from below link and and install Oracle Client and this will solve your problem: https://oracle.github.io/odpi/doc/installation.html#windows
