LAPACK function dgetri_lwork could not be found

Appears when running ./setup.sh in /ncapi. Example traceback (one of many)

Any clues? I already have a Caffe built with BLAS := atlas. Would that be an issue?

@snatch59 Hi, how are you doing? A previous installation of Caffe should not be an issue. I recommend running the toolkit setup.sh script before running the setup.sh script for the API as the toolkit setup.sh script installs other dependencies as well as Caffe. However after using the toolkit setup.sh script, the PYTHONPATH will be set to the Caffe installation that is installed with the SDK. You may edit your bashrc file to point to another Caffe installation and therefore switch to a different Caffe version. Let me know if running the toolkit setup.sh script solves your problem. Thanks.

Hi there. I managed to resolved the issue, with the following steps, with detour back to my own Caffe build and environment.

I re-ran the Toolkit /bin setup.sh using sudo (just in case). I then managed to run the MvNC API /mvnsdk setup.sh (in a new terminal) without the LPACK function error, however I got a number of import Caffe not found errors, despite PYTHONPATH pointing to /opt/movidius/caffe/python.

Due to this weirdness I went back to check my own Caffe build and environment/PYTHONPATH. Running some previous test code incurred the scipy LPACK function dgetri_lwork error. I managed to fix this by completely un-installing scipy and then re-installing the latest version. This led to a different error leading to un-installing scikit-image and the re-installing the latest. Normality restored.

Back to the Movidius Caffe - re-running the MvNC API /mvnsdk setup.sh still led to Caffe no module errors, despite PYTHONPATH being correct. I then ran get_models.sh and covert_models.sh separately and successfully with no import errors.

So I now I have my own Caffe environment and the Movidius one up and running.
