Installation and operational issues

[Josue9740]

I clone the repository and I am finding errore when running the integrity test, and also when running an example code.

This is what I have done (in Anaconda console):

git clone https://github.com/menta78/alphaBetaLab.git
cd alphaBetaLab
python -m unittest test.testAbIntegrity

And this is the output. It seems to be an error with the variable alphaMtx:

Finally, when I run an example like the next one:

import numpy as np
from alphaBetaLab.abOptionManager import abOptions
from alphaBetaLab.abEstimateAndSave import triMeshSpecFromMshFile, abEstimateAndSaveTriangularEtopo1

# Spectral grid
#dirs = np.linspace(0, 2*np.pi, 25)
#nfreq = 25
dirs = np.linspace(0, 2*np.pi, 3)
nfreq = 3
minfrq = .04118
frqfactor = 1.1
freqs = [minfrq*(frqfactor**i) for i in range(1,nfreq + 1)]

# Mesh
gridname = 'ww3'
mshfile = r'D:\Programas\MatLab_codes\Prueba.msh'
triMeshSpec = triMeshSpecFromMshFile(mshfile)

# Bathymetry
etopoFilePath = r'D:\Usuarios\Documentos\ETOPO\ETOPO1_Ice_g_gmt4.grd'

# Output directory
outputDestDir = r'D:\Programas\MatLab_codes'

# Cores in paralel
nParWorker = 2

# Minimum size of the cells
minSizeKm = 5
opt = abOptions(minSizeKm=minSizeKm)

# Computate
abEstimateAndSaveTriangularEtopo1(dirs, freqs, gridname, triMeshSpec, etopoFilePath, outputDestDir, nParWorker)

I get this output/error, which is repeated like in a loop:

    building neighbor cells cache (can take some time) ...
    initializing parallel environment ..

I have installed:
numpy 1.21.5
shapely 1.8
matplotlib 3.5.1
basemap 1.3
netCDF4 1.5.8
scipy 1.7.3
proj 8.2.0
pyproj 3.3.0
Python 3.9.7

I have not proj4 installed, but I guess that proj and pyproj should do the work.

[Josue9740]

I solved this issue by creating a new environment and manually installing every required library, including proj4=5.2.0. It may sound strange, but for this process, avoiding conda-forge installations (except for proj4) worked much better for me. Even in this case, I still have problems when running the test program, but the example codes seem to work properly. In fact, I created my obstruction files for a real case in WW3.

Another problem that I found is that, in order to get the aforementioned obstruction files, I had to fix the nParWorker to 1.
