from zipfile import ZipFile

# Add multiple files to the zip
zipObj.write("checkpoint")
zipObj.write("model_hyperparameters.json")
# close the Zip File
zipObj.close()

ZipfileDotZip = "sample.zip"

with open(ZipfileDotZip, "rb") as f:
    bytes = f.read()
    b64 = base64.b64encode(bytes).decode()
    href = f"<a href=\"data:file/zip;base64,{b64}\" download='{ZipfileDotZip}.zip'>\
        Click last model weights\
    </a>"
st.sidebar.markdown(href, unsafe_allow_html=True)

thanks for this! FYI you forgot to add import base64 :)

hi, do you know, why the zipped file can not be opened..?

Thank you for this! In my program, the user filtrate a data framework using streamlit input, and then downloads one pdf per resulting data frame line. So, I'm trying to create a zip with "on the fly" content, depending on the current filtering. Could you help with that?
