Usage of the program

Hi!

Thanks for this implementation, I have been looking to run it since a couple of days but I can't get it to be done. Is there any tutorial or instructions for somebody who is new to this type of software (and blender)? I tried running bs_render_single.py from IDE, from Conda Prompt, and from blender itself, but nothing seems to work.

Also, I tried to run main.py from windows cmd, from my IDE, and from Conda prompt, but it throws errors in references. I tried changing all the references to match what is being called, but I end up with an error that some files (and the directory optimization) does not exist. Tried to run code from the readme, but still can't get to work.

Would be very helpful if somebody can help me through some basic follow up on how to run this implementation.

Best regards!

Problem in running python script

Hello, I have created the hyperblend environment as mentioned in the readme file but i am not able to import the src . how can i do that?

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
