![]() You will see various text appear in the console. In the bottom-left tab, labelled "Console", type install.packages("tidyverse") and hit enter. Select the installer appropriate for your operating system You should be able to click "Next" to all dialogs to finish the installation. When the file finishes downloading, double-click to install. If you're using gpt-4 you'd want to to set this limit to something much higher.Before the first lecture you should have the following software installed on your machine:įollow these instructions if you have not previously installed R, Rstudio or tidyverse, or if you are unsure. CTXLIM puts an upper bound on the input, by default 2750 tokens, which leaves ~1346 tokens for the response, however, even using OpenAI's tokenizer this can be off by a few tokens (see: 'openai-cookbook'). ![]() ![]() For instance, gpt-3.5-turbo has a limit of 4096 tokens. What does STATGPT_CTXLIM do? Each OpenAI model comes with a token limitation shared between input and response. What does OPENAI_TEMPERATURE do? Temperature ranges 0-2 and controls the level of randomness and creativity in output, with values at or close to 0 being nearly deterministic. It also uses the R packages reticulate, httr, and jsonlite. ![]() StatGPT requires Open AI's tiktoken and therefore Python 3.8 or higher. Sys.setenv(STATGPT_CTXLIM = 2750) # Input context limit (optional default ~2750 tokens)Īlternatively, you can set persistent keys in your. Sys.setenv(STATGPT_DEBUG = 0) # Debug logging (optional default: 0) ![]() Sys.setenv(OPENAI_TEMPERATURE = 0.25) # Temperature (optional default 0.25) Sys.setenv(OPENAI_MODEL = "gpt-3.5-turbo") # Model (optional default: gpt-3.5-turbo) Sys.setenv(OPENAI_API_KEY = "your api key here") # API key ![]()
