UFuncTypeError: Cannot cast ufunc 'add' output from dtype('O') to dtype('float64') with casting rule 'same_kind'

This is my code:
`!pip install paddlepaddle-gpu
!git clone https://github.com/PaddlePaddle/InterpretDL.git
import os
import sys
os.chdir(/content/InterpretDL)
sys.path.insert(0, os.getcwd())
import interpretdl as it
!wget -c https://paddle-imagenet-models-name.bj.bcebos.com/dygraph/ViT_base_patch16_224_pretrained.pdparams -P /content/InterpretDL/tutorials/assets/
from tutorials.assets.vision_transformer import ViT_base_patch16_224
paddle_model = ViT_base_patch16_224()
MODEL_PATH = /content/InterpretDL/tutorials/assets/ViT_base_patch16_224_pretrained.pdparams
paddle_model.state_dict(paddle.load(MODEL_PATH))
img_path = /content/InterpretDL/imgs/catdog.jpg
tam = it.TAMInterpreter(paddle_model)
heatmap = tam.interpret(
img_path,
start_layer=4,
label=None, # cat
visual=True,
save_path=None)'
But i keep getting this error:
UFuncTypeError: Cannot cast ufunc 'add' output from dtype('O') to dtype('float64') with casting rule 'same_kind'
why?

[rojinakashefi]

the problem is from transition_attention_maps.py predict_fn function where attns[-1].grad is None, however i don't know how to fix it

[holyseven]

see if this solves this issue, #52.

let me know if it does not work.

try python -m pip install --force-reinstall paddlepaddle==2.3.2 for the paddle installation issue. Or create a new env to install paddlepaddle

[rojinakashefi]

the thing is paddlepaddle==2.3.2 can't be installed in ubuntu 22.4 and requires ubuntu lower than 20.4.
