Hi Guys! (sorry me again, I’m on a roll with questions today! )
I’m trying to upload tabular data from the file uploader.
Despite using the cache decorator
@st.cache the way Andfanilo described it here, each I move anything (sliders, multi select etc…, see video below), data seems to be constantly re-uploading, which makes the app completely unsuable with any csv with a size greater than 3MB.
Here’s the Python code I’m using:
@st.cache(allow_output_mutation=True) def load_data(file): df = pd.read_csv(file, encoding='utf-8', nrows=50) return df uploaded_file = st.file_uploader("Choose a CSV file", type="csv", key='file_uploader')
I’m not sure if that’s expected - I’m pretty sure I’m doing something sub optimal here!
Thanks in advance!
