bittensor.core.extrinsics.set_weights#
Functions#
|
Internal method to send a transaction to the Bittensor blockchain, setting weights for specified neurons. This method constructs and submits the transaction, handling retries and blockchain communication. |
|
Sets the given weights and values on chain for wallet hotkey account. |

- bittensor.core.extrinsics.set_weights.do_set_weights(self, wallet, uids, vals, netuid, version_key=version_as_int, wait_for_inclusion=False, wait_for_finalization=False)[source]#
Internal method to send a transaction to the Bittensor blockchain, setting weights for specified neurons. This method constructs and submits the transaction, handling retries and blockchain communication.
- Parameters:
self (bittensor.core.subtensor.Subtensor) – Subtensor interface
wallet (bittensor_wallet.Wallet) – The wallet associated with the neuron setting the weights.
uids (list[int]) – List of neuron UIDs for which weights are being set.
vals (list[int]) – List of weight values corresponding to each UID.
netuid (int) – Unique identifier for the network.
version_key (int) – Version key for compatibility with the network.
wait_for_inclusion (bool) – Waits for the transaction to be included in a block.
wait_for_finalization (bool) – Waits for the transaction to be finalized on the blockchain.
- Returns:
A tuple containing a success flag and an optional response message.
- Return type:
This method is vital for the dynamic weighting mechanism in Bittensor, where neurons adjust their trust in other neurons based on observed performance and contributions.
- bittensor.core.extrinsics.set_weights.set_weights_extrinsic(subtensor, wallet, netuid, uids, weights, version_key=0, wait_for_inclusion=False, wait_for_finalization=False)[source]#
Sets the given weights and values on chain for wallet hotkey account.
- Parameters:
subtensor (bittensor.core.subtensor.Subtensor) – Subtensor endpoint to use.
wallet (bittensor_wallet.Wallet) – Bittensor wallet object.
netuid (int) – The
netuid
of the subnet to set weights for.uids (Union[NDArray[np.int64], torch.LongTensor, list]) – The
uint64
uids of destination neurons.weights (Union[NDArray[np.float32], torch.FloatTensor, list]) – The weights to set. These must be
float
s and correspond to the passeduid
s.version_key (int) – The version key of the validator.
wait_for_inclusion (bool) – If set, waits for the extrinsic to enter a block before returning
true
, or returnsfalse
if the extrinsic fails to enter the block within the timeout.wait_for_finalization (bool) – If set, waits for the extrinsic to be finalized on the chain before returning
true
, or returnsfalse
if the extrinsic fails to be finalized within the timeout.
- Returns:
A tuple containing a success flag and an optional response message.
- Return type:
