unable to locate this transaction hash

Version: 4.1.0 Python: 2.7/3.4/3.6 OS: osx/linux/win

What was wrong?

I'm trying to send transaction with the following code:

w3 = Web3(HTTPProvider("https://ropsten.infura.io/gDQS9CITR39Fjvn3WGMD"))
w3.eth.enable_unaudited_features()

address = "0x8e9A...."
MY_PRIVATE_KEY = '0x8ef774e77....'

transaction = {
    'to': address,
    'from': MY_ETH_ADDRESS,
    'value': 0,
    'gas': 2000000,
    'gasPrice': 234567897654321,
    'nonce': int(time.time()),
    'chainId': chainId,
    'data': web3.Web3.toHex(str(some_text))
}

signed = w3.eth.account.signTransaction(transaction, MY_PRIVATE_KEY)
hash = w3.eth.sendRawTransaction(signed.rawTransaction)
print(web3.Web3.toHex(hash))

As result I got txHash, but when I'm trying to find this transaction at etherscan I got nothing (https://ropsten.etherscan.io/tx/0x6e863430e83a22d93ae8181c54e40f309427deb8b1900bae222223d8ca8c173f).

The transaction is not sent and I can't figure out what the problem is. I suppose something wrong with gasPrice. Any suggestions? Thank you!

Each transaction from an address must increment nonce starting at 0. Higher nonces will just sit as pending on the network, until they are eventually included or dropped.
