# Cost Model Calibrator
|
|
|
|
## Python virtual environment
|
|
|
|
The following assumes you are using python from the MongoDB toolchain.
|
|
|
|
```
|
|
/opt/mongodbtoolchain/v4/bin/python3
|
|
```
|
|
|
|
### Getting started
|
|
|
|
Make sure before running `start.py`, you have a locally running `mongod` instance (this must be run using the `mongo-python3` virtual environment, so do it before step 1 below).
|
|
|
|
```sh
|
|
(mongo-python3) deactivate # only if you have another python env activated
|
|
sh> /opt/mongodbtoolchain/v4/bin/python3 -m venv cm # create new env
|
|
sh> source cm/bin/activate # activate new env
|
|
(cm) python -m pip install -r requirements.txt # install required packages
|
|
(cm) python start.py # run the calibrator
|
|
(cm) deactivate # back to bash
|
|
sh>
|
|
```
|
|
|
|
### Install new packages
|
|
|
|
```sh
|
|
(cm) python -m pip install <package_name> # install <package_name>
|
|
(cm) python -m pip freeze > requirements.txt # do not forget to update requirements.txt
|
|
```
