Transport Closed

[kapsali29]

Hi all,

I am trying to execute example usage script, that is demonstrated in iroha-python repo Readme,

from iroha import Iroha, IrohaCrypto, IrohaGrpc

iroha = Iroha('alice@test')
net = IrohaGrpc('127.0.0.1:50051')

alice_key = IrohaCrypto.private_key()
alice_tx = iroha.transaction(
    [iroha.command(
        'TransferAsset', 
        src_account_id='alice@test', 
        dest_account_id='bob@test', 
        asset_id='bitcoin#test',
        description='test',
        amount='1'
    )]
)
IrohaCrypto.sign_transaction(alice_tx, alice_key)
net.send_tx(alice_tx)

for status in net.tx_status_stream(alice_tx):
    print(status)

And I get the above error:

grpc._channel._Rendezvous: <_Rendezvous of RPC that terminated with: status = StatusCode.UNAVAILABLE details = "Transport closed" debug_error_string = "{"created":"@1574768622.626196952","description":"Error received from peer ipv4:127.0.0.1:50051","file":"src/core/lib/surface/call.cc","file_line":1055,"grpc_message":"Transport closed","grpc_status":14}"

Any ideas??

Many thanks
