Webscraping com python

Olá, estou desenvolvendo uma automação em Python com a biblioteca selenium para acessar o site do Econet e retirar os dados de uma tabela a partir de um código de NCM. De inicio escrevi o código para abrir o navegador, acessar a parte do usuário e de pesquisa para NCM's. Porém ao clicar no campo para inserir o NCM me encontro com o seguinte erro:

Traceback (most recent call last):

Segue abaixo o código:

driver = webdriver.Chrome(chromedriver)

url = 'http://www.econeteditora.com.br/'

driver.get(url)
time.sleep(0)

# --- #

time.sleep(2)

time.sleep(2)
