Hey I m using a PDF data loader with

for context i'm importing loaders using this
from llama_index import download_loader

hmmmm

give me one sec

which part is failing for you? the download or the import into vector idnex?

download is failing with:
File "/usr/local/lib/python3.8/site-packages/llama_index/readers/download.py", line 110, in download_loader
spec.loader.exec_module(module) # type: ignore
File "<frozen importlib._bootstrap_external>", line 843, in exec_module
File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
File ".modules/file-pdf.py", line 6, in <module>
from gpt_index.readers.base import BaseReader

ah i see

try refresh_cache=True

this is because the file is cached, it got updated

in the download_loader call

where do i set refresh_cache=True ?
