Mahmoud Abduljawad Comments

I wouldn't suggest this publicly without adding a reference to what that is and what it means. For those reading: https://peps.python.org/pep-0668/ Since many OS depend on Python for system tasks, installing certain packages on default environment could result in conflicts that break the OS itself. For that, this feature was introduced to prevent PIP from modifying default environment. Few others have already made it by using venv and modifying mojo config to point to venv, which is safer on the OS.

please add support for spacy and fastapi

at this stage

I'm sure I read somewhere that Mojo is targeting improving performance on Python modules ran in Mojo. Is that why you ended your comment with that, or am I hallucinating?

Plans for a package manager?

One thing to take into consideration for Mojo package manager when it happens is supply-chain attacks which were used recently in PyPI.

Can I use Python library like huggingface transformer?

You can always try importing any Python library from Mojo and see the aftermath of it:

from python.python import Python
fn main():
  let transformers = Python.import_module("transformers")

from python.python import Python
fn main():
  let transformers = Python.import_module("transformers")

Running twice gives error

This is one interesting case that reminds me of early days of rust becoming mainstream and many users still confused about how ownership and borrow works in it. This conversation here could be elaborated to become a full insightful look at the same with Mojo. Do it, @TeamPuzel.

How to pass Mojo function to Python in Python interop?

I see, @Jack Clayton. I'm trying to offload some of the logic from Python to Mojo to compare performance gains in such cases. Of course this is the simplest explanation, however, I was hoping to start building a sample web application with Mojo built on top of AIOHTTP which won't be possible at the moment due to this limitation. Do I need to open an issue to track this?

How to pass Mojo function to Python in Python interop?

The function returns an object created by python lib, effectively, PythonObject. If I set the return type of function as such, marshalling fails.
