File Directory

Обновлено 28 февраля 2024

This covers how to load all documents in a directory.

from langchain_community.document_loaders import DirectoryLoader

We can use the glob parameter to control which files to load. Note that here it doesn't load the .rst file or the .html files.

loader = DirectoryLoader('../', glob="**/*.md")
docs = loader.load()
len(docs)
    1

Show a progress bar

By default a progress bar will not be shown. To show a progress bar, install the tqdm library (e.g. pip install tqdm), and set the show_progress parameter to True.

loader = DirectoryLoader('../', glob="**/*.md", show_progress=True)
docs = loader.load()
    Requirement already satisfied: tqdm in /Users/jon/.pyenv/versions/3.9.16/envs/microbiome-app/lib/python3.9/site-packages (4.65.0)


0it [00:00, ?it/s]

Use multithreading

By default the loading happens in one thread. In order to utilize several threads set the use_multithreading flag to true.

loader = DirectoryLoader('../', glob="**/*.md", use_multithreading=True)
docs = loader.load()

Change loader class

By default this uses the UnstructuredLoader class. However, you can change up the type of loader pretty easily.

from langchain_community.document_loaders import TextLoader
loader = DirectoryLoader('../', glob="**/*.md", loader_cls=TextLoader)
docs = loader.load()
len(docs)
    1

If you need to load Python source code files, use the PythonLoader.

from langchain_community.document_loaders import PythonLoader
loader = DirectoryLoader('../../../../../', glob="**/*.py", loader_cls=PythonLoader)
docs = loader.load()
len(docs)
    691

Auto detect file encodings with TextLoader

In this example we will see some strategies that can be useful when loading a large list of arbitrary files from a directory using the TextLoader class.

First to illustrate the problem, let's try to load multiple texts with arbitrary encodings.

path = '../../../../../tests/integration_tests/examples'
loader = DirectoryLoader(path, glob="**/*.txt", loader_cls=TextLoader)

A. Default Behavior

loader.load()

</pre>

The file example-non-utf8.txt uses a different encoding, so the load() function fails with a helpful message indicating which file failed decoding.

With the default behavior of TextLoader any failure to load any of the documents will fail the whole loading process and no documents are loaded.

B. Silent fail

We can pass the parameter silent_errors to the DirectoryLoader to skip the files which could not be loaded and continue the load process.

loader = DirectoryLoader(path, glob="**/*.txt", loader_cls=TextLoader, silent_errors=True)
docs = loader.load()
    Error loading ../../../../../tests/integration_tests/examples/example-non-utf8.txt
doc_sources = [doc.metadata['source']  for doc in docs]
doc_sources
    ['../../../../../tests/integration_tests/examples/whatsapp_chat.txt',
'../../../../../tests/integration_tests/examples/example-utf8.txt']

C. Auto detect encodings

We can also ask TextLoader to auto detect the file encoding before failing, by passing the autodetect_encoding to the loader class.

text_loader_kwargs={'autodetect_encoding': True}
loader = DirectoryLoader(path, glob="**/*.txt", loader_cls=TextLoader, loader_kwargs=text_loader_kwargs)
docs = loader.load()
doc_sources = [doc.metadata['source']  for doc in docs]
doc_sources
    ['../../../../../tests/integration_tests/examples/example-non-utf8.txt',
'../../../../../tests/integration_tests/examples/whatsapp_chat.txt',
'../../../../../tests/integration_tests/examples/example-utf8.txt']
