This code below works with nostr_sdk 0.32.2
``` python
import asyncio, argparse, json
from nostr_sdk import Metadata, Client, NostrSigner, Keys, Filter, PublicKey, Kind
from datetime import timedelta
async def main(npub):
client = Client()
await client.add_relay("wss://relay.damus.io")
await client.connect()
pk = PublicKey.from_bech32(npub)
print(f"Getting profile metadata for {npub}:")
f = Filter().kind(Kind(0)).author(pk).limit(1)
events = await client.get_events_of([f], timedelta(seconds=15))
if events:
event = events[0]
metadata_dict = json.loads(event.content())
for key, value in metadata_dict.items():
print(f"{key}: {value}")
else:
print("Could not retrieve metadata for the given public key.")
if __name__ == '__main__':
parser = argparse.ArgumentParser(description='Fetch all metadata for a given npub')
parser.add_argument('npub', type=str, help='The npub of the user')
args = parser.parse_args()
asyncio.run(main(args.npub))
```
but with nostr_sdk 0.39
the program no longer worked and crash with error:
```
AttributeError: type object 'PublicKey' has no attribute
'from_bech32'. Did you mean: 'to_bech32'?
```
why?
