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:
ANSWER
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
in activity this method still work but when i call it in Dialog Fragments, it is deprecated.
Edit:i use the Matisse library for load image , it like
library link: https://github.com/zhihu/Matisse
...ANSWER
Answered 2021-Aug-09 at 02:17First thing is that result activity is deprecated. This is the new way to obtain results from an activity. You should be able to do similarly with a dialog fragment. The reason it was deprecated is because when there is low memory inactive activities are often removed along with the result and this causes errors.
