r-tensorflow / gpt2 Goto Github PK

added to #2

When running:

reticulate::use_condaenv(required = TRUE, condaenv = "r-gpt2")
gpt2::gpt2(model = "124M")

I get

Error in board_pin_store(board, x, name, description, "files", list(extension = extension),  : 
  Client error: (404) Not Found. Failed to download remote file: https://storage.googleapis.com/gpt-2/models/124M/checkpoint

Following that link I get an XML doc that says

<Error>
<Code>NoSuchBucket</Code>
<Message>The specified bucket does not exist.</Message>
</Error>

Not sure, but from here it looks like maybe they moved the models to a new hosting?

remotes::install_github("r-tensorflow/gpt2")

Hi, computer neanderthal here, I have a problem with tensorflow, can u help me plz?

Does it make sense to inform users that models will be stored as pins?
Something like "Downloading ... and storing as ..." when a new model type is downloaded.

Hello,

Thanks a lot for making this available.
I have a question regarding possible values for top_p. From my understanding reading the paper "The curious case of neural text degeneration" (Holtzman et al., 2020), top_p should be a probability between 0 and 1. Yet when I check the code in 'model.R', you turn the value into an integer with as.integer() before providing it to Python.
I tried various values between 0 and 1 with the same seed, and as I expected from the code, the outputs are the same. I get different outputs with values greater than 1, but I can't figure out how things work exactly. Could you please provide some more explanations?

Thanks a lot in advance.
Best,

Christophe C.
