Extracting Device Name from Model using Python Scraping

I am attempting to scrape device information from a specific website (gsmarena) based on its model number. I would like to extract the model name (and eventually price). I'm using a headless browser and rotating proxies to do so, but have had little success in extracting the info. required for ~2000 devices (am able to extract roughly 10 before all IPs blocked).

The (~200) proxies are obtained from https://free-proxy-list.net/, which seem to contain a few that work.

I've explored a number of different options but have had little success. Below is the code I'm currently running- any help would be appreciated.

def get_device_name(device_model, proxies_list):

# Check if the device model is provided, return None if not
if device_model is None:
    return None

# Create a list for storing working proxies
working_proxies = list(proxies_list)

# Start a web driver instance
attempts = 0
while attempts < len(working_proxies):
    proxy = working_proxies[attempts]
    print(proxy)
    try:
        # Set options for the web driver
        options = webdriver.ChromeOptions()
        options.add_argument(f'--proxy-server={proxy}')
        options.add_argument('--headless')
        options.add_argument('--disable-gpu')
        options.add_argument('--no-sandbox')
        options.add_argument('--disable-dev-shm-usage')
        driver = webdriver.Chrome(options=options)

        # Make the request to the website
        url = 'https://www.gsmarena.com/res.php3?sSearch=' + device_model
        driver.get(url)

        # Wait 5 seconds before making another request
        time.sleep(5)

        # Find the device name on the page
        device_name = driver.find_element(By.TAG_NAME, 'strong').text.replace("\n"," ")
        driver.close()
        print(device_name)
        return device_name
    except Exception:
        # If an exception is raised, increment attempts and remove the failed proxy
        attempts += 1
        print("Attempt {} with proxy {} failed. Trying again with a different proxy...".format(attempts, proxy))
        proxies_list.remove(proxy)
        print("Proxy {} removed.".format(proxy))
        continue

# Return None if all attempts failed
print("All attempts failed. Unable to get device name.")
return None

Apply the get_device_name function to the device_model column of user_agents_2

user_agents_3 = user_agents_2 user_agents_3['device_name'] = user_agents_2['device_model'].apply(get_device_name, proxies_list=proxies_list) 
print(user_agents_3)

How to show number of registered users in Laravel based on usertype?

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
