I discovered that one need's to clone the mem-gpt code and pip install -r requirements-local.txt. It downgraded transformers. Now I'm getting a different error. I get TypeError: 'LocalStateManager' object is not subscriptable when I enter memgpt run
pip install demjson3
I have all ready install and import demjson3 module. nut nothing work showing ModuleNotFoundError: No module named 'demjson3'
@Phychotk66 Did you do a pip list? My version is 3.0.6.
@Phychotk66 Did you activate the environment?
@Phychotk66 BYW, memGPT with local models seems incredibly buggy. Fix one error, and you'll get another. This is starting to look like shelfware.

Thank you sir problems are solved
I solved the issue DEFAULT like that :
interface = autogen_interface.AutoGenInterface() # how MemGPT talks to AutoGen persistence_manager = InMemoryStateManager() persona = "I am an engineer at Att3st tech company." human = "I am a team manager at Att3st tech company." agent_config = llm_config memgpt_agent = presets.use_preset(presets.DEFAULT_PRESET, model='gpt-4', persona=persona, human=human, interface=interface, persistence_manager=persistence_manager,agent_config=agent_config)
But Still blocked on the :TypeError: cannot unpack non-iterable coroutine object error
Does anyone have a solution to this?
Yes, modify as mentionned here:
Resolution
I ultimately resolved the issue by modifying the file memgpt/autogen/memgpt_agent.py within my local environment. Specifically, I altered the _generate_reply_for_user_message() function to be asynchronous (async def _generate_reply_for_user_message()). Following this adjustment, the example code operated correctly.

This worked for me perferctly...thanks for this.
running this code I am getting this error.
This seems to be the problem but I can't seem to find the solution this.
import memgpt.presets as presets
...
AttributeError: module 'memgpt.presets' has no attribute 'use_preset'
fixed this problem with this
import memgpt.presets.presets as presets
I met the problem AttributeError: 'dict' object has no attribute 'model_endpoint_type'
I found success after mixing a few of the suggestions above.
- per Matt's video, I created a conda environment using 3.11.3
- I used the absolute path to the conda python env via 'which python' to install only pymemgpt and pyautogen
- Modified the import of presets to
import memgpt.presets.presets as presets
- Modified the code block in app.py to
interface = autogen_interface.AutoGenInterface() # how MemGPT talks to AutoGen
persistence_manager = InMemoryStateManager()
persona = "I am an engineer at Att3st tech company."
human = "I am a team manager at Att3st tech company."
agent_config = llm_config
memgpt_agent = presets.use_preset(presets.DEFAULT_PRESET, model='gpt-4', persona=persona, human=human, interface=interface, persistence_manager=persistence_manager,agent_config=agent_config)
- Modified the MemGPTAgent (memgpt_agent.py) file start at line 229 to:
async def _generate_reply_for_user_message(
self,
messages: Optional[List[Dict]] = None,
sender: Optional[Agent] = None,
config: Optional[Any] = None,
) -> Tuple[bool, Union[str, Dict, None]]:
self.agent.interface.reset_message_list()
new_messages = self.find_new_messages(messages)
if len(new_messages) > 1:
if self.concat_other_agent_messages:
# Combine all the other messages into one message
user_message = "\n".join([self.format_other_agent_message(m) for m in new_messages])
else:
# Extend the MemGPT message list with multiple 'user' messages, then push the last one with agent.step()
self.agent.messages.extend(new_messages[:-1])
user_message = new_messages[-1]
elif len(new_messages) == 1:
user_message = new_messages[0]
else:
return True, self._default_auto_reply
# Package the user message
user_message = system.package_user_message(user_message)
# Send a single message into MemGPT
while True:
(
new_messages,
heartbeat_request,
function_failed,
token_warning,
) = await self.agent.step(user_message, first_message=False, skip_verify=self.skip_verify)
It's now working.

hey mberman84 do you have a new gist that you could share or a repo with a fix?
Also problems with:

how do i solve it
Also problems with: import memgpt.personas.personas as personas import memgpt.humans.humans as humans
Also had this, fixed it. If you slow down the video to 0.25x speed, you can see he installs MemGPT 0.1.3 and AutoGen 0.1.13 at the 2:24 timestamp.
I'm running in a virtual environment on Windows. My commands:
pip uninstall pyautogen
pip uninstall pymemgpt
pip install pyautogen==0.1.13
pip install pymemgpt==0.1.3
Successfully ran original gist.
These things are changing and evolving so quickly, it might be a good idea to mention or post versions in future tutorials. Grateful for all the videos just the same.
EDIT: When I back to play the video, it was still 0.25x speed, highly recommend.
