[Python] Error: '>=' not supported between instances of 'int' and 'str' when searching for...

I'm working on a Python script that uses LangChain and OpenAI to search for machine learning jobs based on my CV. However, I'm encountering the following error:

Error searching for jobs: '>=' not supported between instances of 'int' and 'str'


code:

from langchain_openai import ChatOpenAI
from browser_use import Agent
import asyncio
from dotenv import load_dotenv
import json
import PyPDF2

# Load environment variables (e.g., OpenAI API key)
load_dotenv()

# Function to read a PDF CV
def read_pdf_cv(file_path):
try:
with open(file_path, "rb") as file:
reader = PyPDF2.PdfReader(file)
text = ""
for page in reader.pages:
page_text = page.extract_text()
if page_text: # Check if text extraction was successful
text += page_text
return text
except Exception as e:
print(f"Error reading PDF: {e}")
return ""

async def main():
# Step 1: Read the CV
cv_path = "my_cv.pdf" # Replace with your CV file path
cv_content = read_pdf_cv(cv_path)

if not cv_content:
print("No content extracted from CV. Exiting.")
return

print("CV Content Extracted:", cv_content)

# Initialize the Agent
agent = Agent(
task=f"Read my CV and extract relevant information for ML job applications. CV content: {cv_content}",
llm=ChatOpenAI(model="gpt-4"),
)

# Step 2: Search for ML jobs
try:
ml_jobs = await agent.run("Search for machine learning jobs based on the CV information.")
print("Raw ML Jobs Data:", ml_jobs)

# Ensure all job entries are dictionaries with consistent fields
if isinstance(ml_jobs, list):
for job in ml_jobs:
if isinstance(job, dict):
# Normalize 'salary' field
if 'salary' in job:
try:
job['salary'] = int(job['salary']) # Convert salary to int
except (ValueError, TypeError):
print(f"Invalid salary value for job: {job['salary']}. Setting to 0.")
job['salary'] = 0
else:
print(f"Warning: Job entry is not a dictionary: {job}")
else:
print(f"Error: Expected 'ml_jobs' to be a list, but got {type(ml_jobs)}")
return

except Exception as e:
print(f"Error searching for jobs: {e}")
return

# Step 3: Save the ML jobs to a file
try:
with open("ml_jobs.json", "w") as file:
json.dump(ml_jobs, file, indent=4)
print("ML jobs saved to 'ml_jobs.json'.")
except Exception as e:
print(f"Error saving jobs to JSON: {e}")

# Step 4: Start applying for the jobs in new tabs
for job in ml_jobs:
try:
apply_result = await agent.run(f"Apply for the ML job: {job}. If you need help, ask me.")
print(f"Application Result for {job}:", apply_result)
except Exception as e:
print(f"Error applying for job {job}: {e}")

# Run the main function
if __name__ == "__main__":
asyncio.run(main())


Error Details:

The error occurs in the Step 2: Search for ML jobs section. Specifically, the error message indicates that a comparison (>=) is being attempted between an integer and a string. However, I'm not explicitly using the >= operator in my code, so I suspect it might be happening internally within the Agent or ChatOpenAI logic.

Debugging Attempts:

I added debugging statements to inspect the structure and types of ml_jobs. It appears that ml_jobs is a list of dictionaries, and I ensured that numeric fields like salary are converted to integers.

I also checked if ml_jobs is a list and if each job entry is a dictionary. If not, I added warnings to log the issue.

Environment: Python 3.x

Libraries: langchain-openai, browser-use, python-dotenv, PyPDF2

OpenAI model: gpt-4

Question:

Why is the >= operator being used internally, and how can I resolve this type mismatch?
