\nTo override the default hashing behavior, pass a custom hash function.\nYou can do that by mapping a type (e.g. datetime.datetime) to a hash\nfunction (lambda dt: dt.isoformat()) like this:
\n\nimport streamlit as st\nimport datetime\n\n@st.cache_data(hash_funcs={datetime.datetime: lambda dt: dt.isoformat()})\ndef convert_to_utc(dt: datetime.datetime):\n return dt.astimezone(datetime.timezone.utc)\n\nAlternatively, you can map the type's fully-qualified name\n(e.g. "datetime.datetime") to the hash function instead:
\n\nimport streamlit as st\nimport datetime\n\n@st.cache_data(hash_funcs={"datetime.datetime": lambda dt: dt.isoformat()})\ndef convert_to_utc(dt: datetime.datetime):\n return dt.astimezone(datetime.timezone.utc)\n\n

This means that now the connection object in s1 is the same as in s2.\n\ns3 = get_database_session(SESSION_URL_2)\n# This is a different URL, so the function executes.\n
\nBy default, all parameters to a cache_resource function must be hashable.\nAny parameter whose name begins with _ will not be hashed. You can use\nthis as an "escape hatch" for parameters that are not hashable:
\n\nimport streamlit as st\n\n@st.cache_resource\ndef get_database_session(_sessionmaker, url):\n # Create a database connection object that points to the URL.\n return connection\n\ns1 = get_database_session(create_sessionmaker(), DATA_URL_1)\n# Actually executes the function, since this is the first time it was\n# encountered.\n\ns2 = get_database_session(create_sessionmaker(), DATA_URL_1)\n# Does not execute the function. Instead, returns its previously computed\n# value - even though the _sessionmaker parameter was different\n# in both calls.\n
\nA cache_resource function's cache can be procedurally cleared:
\n\nimport streamlit as st\n\n@st.cache_resource\ndef get_database_session(_sessionmaker, url):\n # Create a database connection object that points to the URL.\n return connection\n\nget_database_session.clear()\n# Clear all cached entries for this function.\n
\nTo override the default hashing behavior, pass a custom hash function.\nYou can do that by mapping a type (e.g. Person) to a hash\nfunction (str) like this:
\n\nimport streamlit as st\nfrom pydantic import BaseModel\n\nclass Person(BaseModel):\n name: str\n\n@st.cache_resource(hash_funcs={Person: str})\ndef get_person_name(person: Person):\n return person.name\n\nAlternatively, you can map the type's fully-qualified name\n(e.g. "__main__.Person") to the hash function instead:
\n\nimport streamlit as st\nfrom pydantic import BaseModel\n\nclass Person(BaseModel):\n name: str\n\n@st.cache_resource(hash_funcs={"__main__.Person": str})\ndef get_person_name(person: Person):\n return person.name\n\n

You can clear a function's cache with func.clear() or clear the entire\ncache with st.cache_resource.clear().

\n\nWhen using this command, Mapbox provides the map tiles to render map\ncontent. Note that Mapbox is a third-party product, the use of which is\ngoverned by Mapbox's Terms of Use.
\nMapbox requires users to register and provide a token before users can\nrequest map tiles. Currently, Streamlit provides this token for you, but\nthis could change at any time. We strongly recommend all users create and\nuse their own personal Mapbox token to avoid any disruptions to their\nexperience. You can do this with the mapbox.token config option.
