I am attempting to replicate the code provided in the documentation of LangChain (URL - 🦜🔗 LangChain 0.0.167) to enable loading HTML files from a list of URLs into a document format, which can then be processed by a sophisticated natural language processing model to perform downstream tasks. However, I have encountered an issue where the code url_data = url_loader.load() hangs for over half an hour without loading any HTML file.
I have also encountered a stack trace and am unable to interpret the error message for the error TP_NUM_C_BUFS too small: 50. This error was previously reported as a resolved issue in the repository of LangChain (link). The author of the issue reported that executing the script that previously caused the TP_NUM_C_BUFS too small: 50 error on Windows command prompt resolved the issue. However, executing my script on Windows command prompt did not resolve the problem.
Would anyone be able to identify the source of this problem and provide a solution?
