Hello All,

I am trying to reset knowledge with the following command from the terminal:

crewai reset-memories --knowledge

It is erroring out with “An unexpected error occurred: No crew found.”

I have tried with upgrading to latest CrewAI version but with no help.

Note: My crew files are not named crew.py, if that could be a reason…

When you run the `crewai reset-memories --knowledge` command, it executes the `reset_memories_command()` function, which is defined [here](https://github.com/crewAIInc/crewAI/blob/04a03d332f00db35a2bb683b2002ecb95b9d5a24/src/crewai/cli/reset_memories_command.py#L8). This, in turn, calls the `get_crews()` function, defined [here](https://github.com/crewAIInc/crewAI/blob/04a03d332f00db35a2bb683b2002ecb95b9d5a24/src/crewai/cli/utils.py#L258), to fetch the crews to be reset. Just by looking at the function’s signature:

```python

def get_crews(crew_path: str = "crew.py", require: bool = False) -> list[Crew]:

```

you can see that, yes, your crew files must be named `crew.py` for the command to work correctly.

This is really interesting… From now on I am going to keep crew.py as my main crew.

Not necessarily. You can use any filename you want, and then perform the reset manually:

```python
my_crew.reset_memories(command_type="all")

```

`command_type` must be one of: `long`, `short`, `entity`, `knowledge`, `agent_knowledge`, `kickoff_outputs`, or `all`.

Thanks for your response. However, when I try to run it from the python process after my crew is defined and before the crew is kicked-off, I get the following error:

RuntimeError: Failed to reset knowledge memory: [Crew (crew)] Failed to reset Crew Knowledge and Agent Knowledge memory: [WinError 32] The process cannot access the file because it is being used by another process: ‘\<path\_to\_knowledge\>\knowledge\chroma.sqlite3’

Any suggestion on how to resolve this?

You’re right, that completely slipped my mind when I suggested that approach.

As soon as you instantiate `crewai.Crew`, its internal memory mechanisms are automatically initialized. This means, for example, that the `chroma.sqlite3` file is locked for the lifetime of the `Crew` object. Therefore, you can’t safely reset the `Crew`’s memory within the same process.

And since the CrewAI CLI doesn’t let you specify a file other than `crew.py`, here’s a simplified version of the original CLI that allows you to reset all memories for `Crew`s in a specific file, like `main.py` or any other. Save it as `reset_crew_memories.py` and then use it like this:

```bash
python reset_crew_memories.py main.py crew1.py my_file.py ...

```

```python

(Full disclosure, I haven’t tested this exhaustively, so good luck! 😄)
