charosen	75fe9d3555	Add from_file method to message prompt template (#4713 ) Feature: This PR adds `from_template_file` class method to BaseStringMessagePromptTemplate. This is useful to help user to create message prompt templates directly from template files, including `ChatMessagePromptTemplate`, `HumanMessagePromptTemplate`, `AIMessagePromptTemplate` & `SystemMessagePromptTemplate`. Tests: Unit tests have been added in this PR. Co-authored-by: charosen <charosen@bupt.cn> Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>	1 year ago

Jonas Nelle	97e7dc1502	Make BaseStringMessagePromptTemplate.from_template return type generic (#4523 ) # Make BaseStringMessagePromptTemplate.from_template return type generic I use mypy to check type on my code that uses langchain. Currently after I load a prompt and convert it to a system prompt I have to explicitly cast it which is quite ugly (and not necessary): ``` prompt_template = load_prompt("prompt.yaml") system_prompt_template = cast( SystemMessagePromptTemplate, SystemMessagePromptTemplate.from_template(prompt_template.template), ) ``` With this PR, the code would simply be: ``` prompt_template = load_prompt("prompt.yaml") system_prompt_template = SystemMessagePromptTemplate.from_template(prompt_template.template) ``` Given how much langchain uses inheritance, I think this type hinting could be applied in a bunch more places, e.g. load_prompt also return a `FewShotPromptTemplate` or a `PromptTemplate` but without typing the type checkers aren't able to infer that. Let me know if you agree and I can take a look at implementing that as well. @hwchase17 - project lead DataLoaders - @eyurtsev	1 year ago
