# Install
|
||
|
||
Let’s start interacting with the python library by firstly installing it & its prerequisites.
|
||
|
||
From the adventurous `Python 3.8.5` all the way up to `Python 3.10.4`, ocean.py has got your back! 🚀
|
||
|
||
While `ocean.py` can join you on your `Python 3.11` journey, a few manual tweaks may be required. But worry not, brave explorers, we've got all the juicy details for you below! 📚✨\
|
||
\
|
||
⚠️ Make sure that you have `autoconf`, `pkg-config` and `build-essential` or their equivalents installed on your host.
|
||
|
||
### Installing ocean.py
|
||
|
||
ocean.py is a Python library [on pypi as ocean-lib](https://pypi.org/project/ocean-lib/). So after you have completed the prerequisites step, let's create a new console for library installation:
|
||
|
||
```bash
|
||
# Create your working directory
|
||
mkdir my_project
|
||
cd my_project
|
||
|
||
# Initialize virtual environment and activate it. Install artifacts.
|
||
# Make sure your Python version inside the venv is >=3.8.
|
||
# Anaconda is not fully supported for now, please use venv
|
||
python3 -m venv venv
|
||
source venv/bin/activate
|
||
|
||
# Avoid errors for the step that follows
|
||
pip install wheel
|
||
|
||
# Install Ocean library.
|
||
pip install ocean-lib
|
||
```
|
||
|
||
### Potential issues & workarounds <a href="#60e8" id="60e8"></a>
|
||
|
||
Issue: M1 \* `coincurve` or `cryptography`
|
||
|
||
* If you have an Apple M1 processor, `coincurve` and `cryptography` installation may fail due missing packages, which come pre-packaged in other operating systems.
|
||
* Workaround: ensure you have `autoconf`, `automake` and `libtool` installed as it is mentioned in the prerequisites, e.g. using Homebrew or MacPorts.
|
||
|
||
Issue: MacOS “Unsupported Architecture”
|
||
|
||
* If you run MacOS, you may encounter an “Unsupported Architecture” issue.
|
||
* Workaround: install including ARCHFLAGS: `ARCHFLAGS="-arch x86_64" pip install ocean-lib`. [Details](https://github.com/oceanprotocol/ocean.py/issues/486).
|
||
|
||
To install ocean-lib using Python 3.11, run `pip install vyper==0.3.7 --ignore-requires-python` and `sudo apt-get install python3.11-dev` before installing ocean-lib. Since the parsimonious dependency does not support Python 3.11, you need to edit the `parsimonious/expressions.py` to `import getfullargspec as getargsspec` instead of the regular import. These are temporary fixes until all dependencies are fully supported in Python 3.11. We do not directly use Vyper in ocean-lib.

||
### ocean.py uses Brownie
|
||
|
||
Let's dive deeper into the Ocean world! 💙 Did you know that Ocean and Brownie are like best buddies? When you installed Ocean (ocean-lib pypi package) earlier, it automatically took care of installing Brownie (eth-brownie package) too. Talk about a dynamic duo! 🦸♀️🦸♂️
|
||
|
||
`ocean.py` treats each Ocean smart contract as a Python class, and each deployed smart contract as a Python object. We love this feature, because it means Python programmers can treat Solidity code as Python code! 🤯

### Helpful resources
|
||
|
||
Oh, buoy! 🌊🐙 When it comes to installation, ocean.py has you covered with a special README called ["install.md"](https://github.com/oceanprotocol/ocean.py/blob/main/READMEs/install.md). It's like a trusty guide that helps you navigate all the nitty-gritty details. So, let's dive in and ride the waves of installation together! 🏄♂️🌊
