Streamlit failed to hash an object #242
Description
I am trying to get the DataFrame Demo from streamlit hello to work. I am running this using Anaconda and Python 3.6.
I get the following error in the browser:
Streamlit cannot hash an object of type <class 'os._Environ'>.,
More information: to prevent unexpected behavior, Streamlit tries to detect mutations in cached objects so it can alert the user if needed. However, something went wrong while performing this check.
Please file a bug.
To stop this warning from showing in the meantime, try one of the following:
Preferred: modify your code to avoid using this type of object.
Or add the argument ignore_cache=True to the st.cache decorator.
I get a bunch of additional errors on Streamlit failed to hash an object of type <class 'function'>.,
And then this error blob:
TypeError: object supporting the buffer API required
