QUESTION
I just got my new MacBook Pro with M1 Max chip and am setting up Python. I've tried several combinational settings to test speed - now I'm quite confused. First put my questions here:
- Why python run natively on M1 Max is greatly (~100%) slower than on my old MacBook Pro 2016 with Intel i5?
- On M1 Max, why there isn't significant speed difference between native run (by miniforge) and run via Rosetta (by anaconda) - which is supposed to be slower ~20%?
- On M1 Max and native run, why there isn't significant speed difference between conda installed Numpy and TensorFlow installed Numpy - which is supposed to be faster?
- On M1 Max, why run in PyCharm IDE is constantly slower ~20% than run from terminal, which doesn't happen on my old Intel Mac.
Evidence supporting my questions is as follows:
Here are the settings I've tried:
1. Python installed by
- Miniforge-arm64, so that python is natively run on M1 Max Chip. (Check from Activity Monitor,
Kind
of python process isApple
). - Anaconda. Then python is run via Rosseta. (Check from Activity Monitor,
Kind
of python process isIntel
).
2. Numpy installed by
conda install numpy
: numpy from original conda-forge channel, or pre-installed with anaconda.- Apple-TensorFlow: with python installed by miniforge, I directly install tensorflow, and numpy will also be installed. It's said that, numpy installed in this way is optimized for Apple M1 and will be faster. Here is the installation commands:

Answered 2021-Dec-06 at 05:53Since the benchmark is running linear algebra routines, what is likely being tested here are the BLAS implementations. A default Anaconda distribution for osx-64 platform is going to come with Intel's MKL implementation; the osx-arm64 platform only has the generic Netlib BLAS and the OpenBLAS implementation options.
For me (MacOS w/ Intel i9), I get the following benchmark results:
BLAS Implmentation Mean Timing (s)mkl
0.95932
blis
1.72059
openblas
2.17023
netlib
5.72782
So, I suspect the old MBP had MKL installed, and the M1 system is installing either Netlib or OpenBLAS. Maybe try figuring out whether Netlib or OpenBLAS are faster on M1, and keep the faster one.
Specifying BLAS ImplementationHere are specifically the different environments I tested:

QUESTION
Does it make sense to use Conda + Poetry for a Machine Learning project? Allow me to share my (novice) understanding and please correct or enlighten me:
As far as I understand, Conda and Poetry have different purposes but are largely redundant:
- Conda is primarily a environment manager (in fact not necessarily Python), but it can also manage packages and dependencies.
- Poetry is primarily a Python package manager (say, an upgrade of pip), but it can also create and manage Python environments (say, an upgrade of Pyenv).
My idea is to use both and compartmentalize their roles: let Conda be the environment manager and Poetry the package manager. My reasoning is that (it sounds like) Conda is best for managing environments and can be used for compiling and installing non-python packages, especially CUDA drivers (for GPU capability), while Poetry is more powerful than Conda as a Python package manager.
I've managed to make this work fairly easily by using Poetry within a Conda environment. The trick is to not use Poetry to manage the Python environment: I'm not using commands like poetry shell
or poetry run
, only poetry init
, poetry install
etc (after activating the Conda environment).
For full disclosure, my environment.yml file (for Conda) looks like this:
...ANSWER
Answered 2022-Feb-14 at 10:04As I wrote in the comment, I've been using a very similar Conda + Poetry setup in a data science project for the last year, for reasons similar to yours, and it's been working fine. The great majority of my dependencies are specified in pyproject.toml
, but when there's something that's unavailable in PyPI, I add it to environment.yml
.
Some additional tips:
- Add Poetry, possibly with a version number (if needed), as a dependency in
environment.yml
, so that you get Poetry installed when you runconda env create
, along with Python and other non-PyPI dependencies. - Consider adding
conda-lock
, which gives you lock files for Conda dependencies, just like you havepoetry.lock
for Poetry dependencies.
