Unable to install openpose. fatal error: 'cblas.h' file not found #include <cblas.h> . arm64 (m1 mac)

Issue Summary

I am unable to install openpose. I keep getting an error that cblas.h was not found. The output is below.

I followed all steps to prereqs and upto compilation, here, and I get stopped at the final step. There's an error saying cblas.h is not found. I also tried building caffe seperately as instructed here below but no luck. Still get the cblas.h error again. I have an arm64 cpu (Apple M1 Pro), running on macOS Monterey 12.2.1. I am using python 3.9.10 with pyenv.

I feel like i've exhausted all my options, is there anything else I should try?

Executed Command (if any)

• install prereqs, and clone openpose instructions

cd build/
make -j`sysctl -n hw.logicalcpu`

Errors (if any)

.../openpose/build/caffe/include/caffe/util/mkl_alternate.hpp:14:10: fatal error: 'cblas.h' file not found
#include <cblas.h>

Getting the same error!! Stuck on it since a long time, any resolutions?

What OS, CPU, and GPU do you use, and is your python installed via pyenv?

You can check issue #1942

Solved by modifying the CMakeLists.txt file as introduced in #1942 In case you face more errors you can refer to the changes I did for building OpenPose with Caffe uploaded to this repository. All changes are grouped in the commit e0e5833. The steps I followed for a successful installation in my Mac M1 are displayed in the Readme. I hope M1 Mac users can find this helpful.
