I'm using VSCode with Python 3.11.0 in a virtual enviroment. I have installed the aforementioned toolchain to configure and launch LTSpice models.

However, it seems not to work and I cannot find why (I'm quite new to python programming). I attach here the actual code and the traceback. Notice that the main code is taken from the example given in its webpage.

The code:

import os
from PyLTSpice.LTSpiceBatch import SimCommander

# get script absolute path
meAbsPath = os.path.dirname(os.path.realpath("Draft1.asc"))
meAbsPath = meAbsPath + '/Draft1.asc'
print(str(meAbsPath))


# select spice model
LTC = SimCommander(meAbsPath)

# set default arguments
# LTC.set_parameters(res=0, cap=100e-6)
LTC.set_component_value('R1', '2k')
LTC.set_component_value('L1', '1u')
# LTC.set_element_model('V3', "SINE(0 1 3k 0 0 0)")
# define simulation
LTC.add_instructions(
    "; Simulation settings",
    ".param run = 0"
)

LTC.reset_netlist()
LTC.add_instructions(
    "; Simulation settings",
    ".tran 0 10u 0 1n",
)

LTC.run()
LTC.wait_completion()

# Sim Statistics
print('Successful/Total Simulations: ' + str(LTC.okSim) + '/' + str(LTC.runno))

The traceback log:

FileNotFoundError: [WinError 2] El sistema no puede encontrar el archivo especificado

I guess that it actually finds the ".asc" LTSpice model file, but at some point it misses something but I could not figure out what is it. Thanks in advance!
