Cannot reproduce results from notebook on Colab
Opened this issue · 3 comments
Describe the bug
Running the KerasNLP guide in Colab, I get more or less 50% classification accuracy, i.e. no better than a random classifier. It get the same when fine-tuning the classifier. I am making no changes to any code in the notebook. Just running the code.
To Reproduce
Link to the Colab Notebook, which reproduces the bug.
Expected behavior
I expected to get the same accuracy results as reported in the text, i.e., around 78% accuracy for the first example.
Hi @jespernwulff ,
I have replicated the issue and attached gist here.
In the generated documentation guide the sparse_categorical_accuracy
touced to 0.8443
in 2nd epoch but when trained now it is staying at 0.5
only even in epoch 3.
Hi @jespernwulff!
Thanks for reporting this issue! I'll look into it!
I think the issue is related to the dataset. I also got around 50% accuracy when I ran the fine-tuning with the IMDB dataset downloaded in the guide but when I switched to loading the IMDB dataset from tensorflow_datasets
, I got 87% accuracy.
I'll update the guide to get the IMDB dataset from tensorflow_datasets
for now.
