oceanai-py 0.0.5

Librería para conectarce a ocean protocol y poder crear IA

Oceanai-py

Wrapper library that allows a direct integration between the Ocean marketplace and artificial intelligence tools like tensorflow

With Oceanai-py, you can:

• Create artificial intelligence models: the current state of the library uses Tensorflow for the implementation of the AI models, anything that you can do with Tensorflow you can also do it with Oceanai-py

• Buy OCEAN marketplace datasets to use them on your models

• Consume OCEAN datatokens, to access the services of the Ocean environment.

Every function related to the OCEAN environment is fullfiled using Ocean.py. Ocean.py is part of the Ocean Protocol toolset.

This library is still in alpha state and you can expect running into problems.

📚 Prerequisites

• Python (recomended version 3.9) (Install from here)

🏗 Installation

#Is necesary to install tensorflow  and ocean-lib separately for aboiding download errors.
pip install oceanai-py
pip install tensorflow
pip install --pre ocean-lib

🏄 Quickstart

The source code of this example is also included on the folder samples of the library

index.py This file explains how to implement several types of AI models for the selected Ocean dataset

Obtaining Ocean datasets

In here we will explain how to obtain OCEAN datasets using oceanai-lib.

from src.ocean.occean import Occean

d = {
   'network' : 'https://rinkeby.infura.io/v3/proyectid',
   'metadataCacheUri' : 'https://v4.aquarius.oceanprotocol.com',
   'providerUri' : 'https://v4.provider.rinkeby.oceanprotocol.com',
}

occean = Occean(d,"private key my account","private key accout buying from")

# create NFT token in the accoutn buying from
data_nft = occean.publishNFTToken('NFTToken1', 'NFT1')
##occean.createDatasetExmple()
# the account we are buying from create the datatoken 
datatoken = occean.createDataToken(data_nft,2)
#datatoken = occean.getDatatoken('token address') we can allso get the datatoken 
#creat exage id an the buy
exange_id = occean.getExchangeId(datatoken,1,3)
tx_result = occean.buy(datatoken,exange_id,1,2)
