FileNotFoundError: Could not find 400.0 nm image from /home/XXX/dev/HyperBlend/leaf_measurement_sets/try_p_leaves/sample_results/sample_0/working_temp/rend.

Hello,
I have installed HyperBlend from git with git clone and anaconda in ubuntu.
I have run this code :

from src.leaf_model import interface as LI

set_name = "try_random_p_leaves"

# generates three leaf targets to \HyperBlend\leaf_measurement_sets\try_random_p_leaves\sample_targets
LI.generate_prospect_leaf_random(set_name=set_name, count=3)

# Solve renderable leaf material parameters that produce target reflectance and transmittance
LI.solve_leaf_material_parameters(set_name=set_name, resolution=10, solver='nn')

# After solver has run, check results from HyperBlend\leaf_measurement_sets\try_random_p_leaves\set_result

As a result, it is showing this error

FileNotFoundError: Could not find 400.0 nm image from /home/maroun/dev/HyperBlend/leaf_measurement_sets/try_manual_set/sample_results/sample_0/working_temp/rend.

Could you please try to help us solve it?
Thank you

Best,

Hello Maroun, and sorry for super late response! I didn't notice your issue as I thought no one is using HyperBlend.

The error message at the bottom says that it is trying to find the rendered band from try_manual_set/.. directory, which
does not exist if you haven't run the code in "Real world measurements" section of the README. Can you check that you passed set_name = "try_random_p_leaves" when you called LI.solve_leaf_material_parameters() and not "set_name = try_manual_set".
