ERROR: poppler no found on variable PATH

Hello everyone,

I'm facing an issue with a Python function embedded in a Dataiku API. The business case involves applying OCR to PDFs, and I'm encountering two problems:

1. The PATH environment variable throws an error, stating that it cannot find the poppler-utils library within that variable.

2. Failed: Failed to run function: <class 'pytesseract.pytesseract.TesseractNotFoundError'>: [Errno None] None: 'None'. The Python code I'm developing is:

from flask import Flask, jsonify, request
from pprint import pprint
import numpy as np
import pandas as pd
#import requests
import json
from decimal import Decimal
from flask_cors import CORS
from datetime import datetime
import Functions_EVision as EVision
from pdf2image.exceptions import PDFPageCountError
import os
from os import environ as env
from dotenv import load_dotenv
from pdf2image import convert_from_path, convert_from_bytes
from urllib.request import Request, urlopen
import io #from memory files to bytes

import ssl
from urllib.request import Request, urlopen

# Deshabilitar verificación de certificado SSL
context = ssl.create_default_context()
context.check_hostname = False
context.verify_mode = ssl.CERT_NONE

def predict(Path,OutputType,NumPages):

remote_file = urlopen(Request(ruta), context=context).read()
print('remote file generated')
try:
print('try pdf')
ObjetoImagen = convert_from_bytes(remote_file
, 350
#,poppler_path = path_Poller_pdf2image
)
extension = 'PDF'
except PDFPageCountError :
print('try image')
ObjetoImagen = ' '
extension = ' '

print('try EVIsion')
Text = EVision.EVision_OCRModel(path = ruta
, ExtensionDoc = extension
, NumPages = NumPages
, ImageObject = ObjetoImagen
, TipoOutput = OutputType
)

mensaje = {
"Document_Text" : Text[0],
"Accuracy" : Text[1]
}

t_f=datetime.now()
TimeRunning = t_f-t_0
delta_seg = TimeRunning.total_seconds()
delta_min = delta_seg/60
print('Execution time', delta_seg , 'sec')
print('Execution time', delta_min , 'min')

return jsonify(mensaje)

Thanks in adanced for your assistance.
