encountered error when using load_chain

[xin007-kong]

When I exectuted the code below

from langchain.chains import load_chain

chain = load_chain("lc://chains/llm-math/chain.json")

I met the following error
ValueError: Could not find file at https://raw.githubusercontent.com/hwchase17/langchain-hub/master/chains\llm-math\chain.json

based of path you have pasted looks like the path is wrong, post \llm-math\chain.json

I think chain = load_chain(r"lc://chains/llm-math/chain.json") will work

anyhow it is deprecated
