iswariyam opened a new issue #6287:
URL: https://github.com/apache/incubator-tvm/issues/6287
The following error occurs when feeding a tensorflow 2.3 compiled model to
relay.frontend.from_keras()
`AttributeError: 'Node' object has no attribute 'node_indices'`
The following code can be used to reproduce the error.
```
import numpy as np
import tensorflow as tf
import tensorflow.keras as keras
from matplotlib import pyplot as plt
from PIL import Image
from tensorflow.keras.applications.resnet50 import preprocess_input
import tvm
import tvm.relay as relay
from tvm import te
from tvm.contrib.download import download_testdata
keras_resnet50 = keras.applications.resnet50.ResNet50(
include_top=True, input_shape=(224, 224, 3), classes=1000
)
img_url =
"https://github.com/dmlc/mxnet.js/blob/master/data/cat.png?raw=true";
img_path = download_testdata(img_url, "cat.png", module="data")
img = Image.open(img_path).resize((224, 224))
# input preprocess
data = np.array(img)[np.newaxis, :].astype("float32")
data = preprocess_input(data).transpose([0, 3, 1, 2])
print("input_1", data.shape)
shape_dict = {"input_1": data.shape}
mod, params = relay.frontend.from_keras(keras_resnet50, shape_dict)
```
**Reason**
The issue occurs due to changes in the attributes of the Node class in
[tensorflow
2.3](https://github.com/tensorflow/tensorflow/blob/r2.3/tensorflow/python/keras/engine/node.py)
as compared to [tensorflow
2.2](https://github.com/tensorflow/tensorflow/blob/r2.2/tensorflow/python/keras/engine/node.py)
**Environment**:
- Python : 3.7.7
- Tensorflow : 2.3
- TVM : 0.7.dev1
- OS : Ubuntu 16.04
