The folder "edges" can be run on MATLAB 2017B UBUNTU 16.04.3 
lsb_release -a : check version of UBUNTU

1. Download toolbox https://github.com/pdollar/toolbox , compile by ">>toolboxCompile;"
2. Compile: mex private/e*.cpp -outdir private '-DUSEOMP' CFLAGS="\$CFLAGS -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp"

Change int to mwSize in all *.cpp files

e.g. edgesDetectMex.cpp 

Error: cannot convert 'const int*' to 'const size_t*'; requested 54329384 * 11234123 (17**.GB)array exceeds maximum array size preference. See array size limit or preference panel for more information. 

Reason: the argument should be type size_t*, but be int*

Solution: int -> mwSize

details: 
   Line 74, 78, 83,84, 87,88,89 type const int -> const mwSize

Then compile:
mex private/edgesDetectMex.cpp -outdir private '-DUSEOMP' CFLAGS="\$CFLAGS -fopenmp" LDFLAGS="\$LDFLAGS -fopenmp"

Another example: spDetectMex.cpp line 324 const int dims[3] -> const mwSize dims[3]

To use the toolbox, addpath(genpath('./toolbox/')); savepath; 

Error: invalid mex-file Function mexFunction is missing
Reason: "mexFunction" or the parameters may be incorrect, make sure

Void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[] )


Jupyter notebook cannot recognize tensorflow

Solution:
conda install -c bioconda bcbio-nextgen
bcbio_conda install c condo-forge libsodium
       

Update tensor flow:

Conda update -f -c condo-forge tensorflow

Install panda3d GitHub:/panda3d/panda3d

Pip show tensorflow

Install from tensorflow from source
