Description
I only download torchs and i do not have tensorflow.
I had thought it was a matter of not successfully modifying the backend. But I found out through the output that the modification was successful. It seems that some functions inside keras-nlp are written using tensorflow. I'm guessing this is the issue and would appreciate your attention and answers.
torch 2.1.0
torchaudio 2.1.0
torchvision 0.16.0
cuda11.8/toolkit/11.8.0
cudnn8.5-cuda11.8/8.5.0.96
/home/name/.keras/keras.json
I try KERAS-HOME and KERAS-BACKEND
{
"floatx": "float32",
"epsilon": 1e-07,
"backend": "torch",
"image_data_format": "channels_last"
}
from keras import backend as K
print(K.backend()) # torch
maybe the key is keras-nlp
