"Datasets can be created in a number of ways, most often by collecting `Run`'s captured through the LangChain tracing API and converting a set of runs to a dataset.\n",

"The V2 tracing API is currently accessible using the `tracing_v2_enabled` context manager. Assuming the server was succesfully started above, running LangChain Agents, Chains, LLMs, and other primitives will then automatically capture traces. We'll start with a simple math example."

"**Note** You can also use the `LANGCHAIN_TRACING_V2` environment variable to enable tracing for all runs by default, regardless of whether or not those runs happen within the `tracing_v2_enabled` context manager (i.e. `os.environ[\"LANGCHAIN_TRACING_V2\"] = \"true\"`)"
