Your app is having trouble loading the extra_streamlit_components.CookieManager.cookie_manager component.

[ihpolash]

I'm trying to implement login option on my app. But getting this error & can't login to the main body.

Please help.

(The app is attempting to load the component from ****, and hasn't received its "streamlit
" message.)

If this is a development build, have you started the dev server?
If this is a release build, have you compiled the frontend?
For more troubleshooting help, please see the [Streamlit Component docs](https://docs.streamlit.io/library/components) or visit our [forums](https://discuss.streamlit.io/).```

Hi @ihpolash can you please share your code?

[ihpolash]

@mkhorasani Here is the code. I've implemented under pages/train.py

import streamlit as st
import streamlit_authenticator as stauth

import yaml
from yaml.loader import SafeLoader

# hashed_passwords = stauth.Hasher(['abc']).generate()
st.set_page_config(initial_sidebar_state="collapsed")

with open('config.yaml') as file:
    config = yaml.load(file, Loader=SafeLoader)

st.markdown(
    """
<style>
    [data-testid="collapsedControl"] {
        display: none
    }
</style>
""",
    unsafe_allow_html=True,
)

hide_menu = """
<style>
#MainMenu {
    visibility:hidden;
}

footer{
    visibility:hidden;
}

</style>
"""

def main():

    authenticator = stauth.Authenticate(
          config['credentials'],
          config['cookie']['name'],
          config['cookie']['key'],
          config['cookie']['expiry_days'],
          config['preauthorized']
      )

    name, authentication_status, username = authenticator.login('Login', 'main')

    st.markdown(hide_menu, unsafe_allow_html=True)
    if authentication_status:
        authenticator.logout('Logout', 'main', key='unique_key')
        # st.markdown('<h1 style="color:black;">Model Training</h1>', unsafe_allow_html=True)
        # st.markdown('<h2 style="color:gray;">Upload dataset</h2>', unsafe_allow_html=True)
        # set_png_as_page_bg('bg.jpg')

        upload= st.file_uploader('Insert zip file for training', type=['zip'])

        extract_dir = 'data'
        if upload is not None:
            # Unzip the file
            unzip_file(upload, extract_dir)

            hist = train_test_data_gen()

            fig, ax = plt.subplots()
            ax.plot(hist.history['accuracy'])
            ax.plot(hist.history['val_accuracy'])
            ax.set_title('model accuracy')
            ax.set_ylabel('accuracy')
            ax.set_xlabel('epoch')
            # ax.set_legend(['train', 'val'], loc='upper left')
            st.pyplot(fig)
            K.clear_session()

    elif authentication_status is False:
        st.error('Username/password is incorrect')
    # elif authentication_status is None:
    #     st.warning('Please enter your username and password')

if __name__ == "__main__":
    main()

any follow up on this? I think the cookie manager is not updated to account for some deprecations in Streamlit cache system.

[borisko123]

the same for me

[ibehnam]

any update from the developer?

[mkhorasani]

Dear all I have made the following PR to the developer to update the library. Please stay tuned.
