trying to multithread scraping a bunch of urls with requests-html but it isnt exactly working any idea how to fix this? ` def get_dynamic_content(url_obj:URLObject, req_parameters_obj:RequestParameters): reqh = HTMLSession() if url_obj.request_type == "get": r = reqh.get(url_obj.url) r.html.render() reqh.close() return r.html ` when i try to run this in threaded version ` tpool = ThreadPool(processes=int(config_data['max thread count'])) ` ` def start_scraping(): out = tpool.map(get_dynamic_content, toscrape) tpool.close() tpool.join() print(out) ` it just throws the mentioned error is there any fix?
