William FH	131c043864	Fix loading of ImagePromptTemplate (#16868 ) We didn't override the namespace of the ImagePromptTemplate, so it is listed as being in langchain.schema This updates the mapping to let the loader deserialize. Alternatively, we could make a slight breaking change and update the namespace of the ImagePromptTemplate since we haven't broadly publicized/documented it yet..	7 months ago

Christophe Bornet	a0ec045495	Add async methods to BaseStore (#16669 ) - Description: The BaseStore methods are currently blocking. Some implementations (AstraDBStore, RedisStore) would benefit from having async methods. Also once we have async methods for BaseStore, we can implement the async `aembed_documents` in CacheBackedEmbeddings to cache the embeddings asynchronously. * adds async methods amget, amset, amedelete and ayield_keys to BaseStore * implements the async methods for InMemoryStore * adds tests for InMemoryStore async methods - Twitter handle: cbornet_	7 months ago
