Import RobustQuadraticSolverCython Error
Hi, Thank you for all your work !
I had ran the ./build.sh file and it turned out many warings. I choose to ignore this warnings and run the demo.py ,then it didn't work with the error below , can you give me some suggestion?Thank you !
root@desktop:/home/hh/pca# python demo.py /home/hh/pca/pcaflow Traceback (most recent call last): File "demo.py", line 3, in <module> from pcaflow import PCAFlow File "/home/hh/pca/pcaflow/PCAFlow.py", line 35, in <module> from solver.RobustQuadraticSolverCython import RobustQuadraticSolverCython as RobustQuadraticSolver ImportError: /home/hh/pca/pcaflow/solver/RobustQuadraticSolverCython.so: undefined symbol: dgetri_
Unable to run demo.py
Hi,
I am able to normally compile with build.sh. However, when running demo.py I am getting the following python error
Re-allocating matcher...

Warnings affect the result?
Thank you so much for sharing your code.
When I run PCA_Layers, it returns 2 warnings:
~/anaconda3/envs/pca/lib/python2.7/site-packages/sklearn/utils/deprecation.py:77: DeprecationWarning: Function log_multivariate_normal_density is deprecated; The function log_multivariate_normal_density is deprecated in 0.18 and will be removed in 0.20.

warnings.warn(msg, category=DeprecationWarning)
Do these warning affect the output?
Thank you.

Hello,
Your code looks awesome! I'm trying to get it running on my machine, and I'm bumping into this error: not sure what I'm doing wrong?
On a Linux Ubuntu 16.04 machine, ran the build.sh script, appear to have prerequisites installed.
