The right way to install Pymilvus

Updated 2 years ago on July 18, 2023

Installing with pip

PyMilvus is found in the Python package index.

PyMilvus only supports python3 (>= 3.6), typically PyMilvus can be installed as follows.

$ python3 -m pip install pymilvus

Installation in a virtual environment

It is recommended to use PyMilvus in a virtual environment. Using a virtual environment avoids global installation of Python packages, which can break system tools or other projects. To demonstrate installing and using PyMilvus in a virtual environment, we use virtualenv. For more information on why and how, see the virtualenv article.

$ python3 -m pip install virtualenv $ virtualenv venv $ source venv/bin/activate (venv) $ pip install pymilvus

If you need to exit virtualenv venv, you can use the deactivate command.

Installing a specific version of PyMilvus

Here we are assuming that you are already in a virtual environment.

The appropriate version of PyMilvus depends on the version of Milvus you are using. See install pymilvus for the recommended version of pymilvus.

If you want to install a particular version of PyMilvus:

(venv) $ pip install pymilvus==1.1.0

If you want to upgrade PyMilvus to the latest published version:

(venv) $ pip install --upgrade pymilvus

Installation from source code

As a result, the latest version of PyMilvus will be installed in the virtual environment.

(venv) $ pip install git+https://github.com/milvus-io/pymilvus.git

Installation check

Your installation is correct if the following command does not raise an exception in the Python shell.

(venv) $ python -c "from milvus import Milvus, DataType"

Why is stable diffusion better? Updated 2 years ago

Although DALL-E 2 is the best known in the field of AI image generation, it might make sense to try Stable Diffusion first: it has a free trial, it's cheaper, it's more powerful, and it has wider usage rights. If you get completely sidetracked, you can also use it to develop your own generative AI.

What is the stable diffusion method? Updated 2 years ago

Stable Diffusion is a hidden diffusion model, a type of deep generative artificial neural network. Its code and model weights are published in the public domain, and it can run on most consumer hardware equipped with a modest GPU with at least 8 GB of VRAM.
