All you need to do is install pillow: Then you should be all set. Found this after hours of searching.
Tensorflow 2.0 – AttributeError: module ‘tensorflow’ has no attribute ‘Session’
According to TF 1:1 Symbols Map, in TF 2.0 you should use tf.compat.v1.Session() instead of tf.Session() https://docs.google.com/spreadsheets/d/1FLFJLzg7WNP6JHODX5q8BDgptKafq_slHpnHVbJIteQ/edit#gid=0 To get TF 1.x like behaviour in TF 2.0 one can run but then one cannot benefit of many improvements made in TF 2.0. For more details please refer to the migration guide https://www.tensorflow.org/guide/migrate
NaN loss when training regression network
Regression with neural networks is hard to get working because the output is unbounded, so you are especially prone to the exploding gradients problem (the likely cause of the nans). Historically, one key solution to exploding gradients was to reduce the learning rate, but with the advent of per-parameter adaptive learning rate algorithms like Adam, you no … Read more
getting ValueError : “Can only tuple-index with a MultiIndex “
You have problem with i:(i+window_size), 0 in dataset[i:(i+window_size), 0]. In your code dataset means train_data[‘seq’] which is single column – single-dimensional Series – but you use i:(i+window_size), 0 like in two-dimensional DataFrame. You can use only single integer like dataset[0] or slice dataset[i:(i+window_size)]
ImportError: cannot import name np_utils
I’m trying to run the following example from keras but I get this error: I’m using Ubuntu and I installed keras with: This question was already asked but there was no answer: Keras: Cannot Import Name np_utils
Cross Validation in Keras
If my goal is to fine-tune the network for the entire dataset It is not clear what you mean by “fine-tune”, or even what exactly is your purpose for performing cross-validation (CV); in general, CV serves one of the following purposes: Model selection (choose the values of hyperparameters) Model assessment Since you don’t define any … Read more
How to fix “AttributeError: module ‘tensorflow’ has no attribute ‘get_default_graph'”?
Please try: from tensorflow.keras.models import Sequential instead of from keras.models import Sequential
Get Confusion Matrix From a Keras Multiclass Model
Your input to confusion_matrix must be an array of int not one hot encodings.
AttributeError: ‘Tensor’ object has no attribute ‘_keras_history’
I looked for all the “‘Tensor’ object has no attribute ***” but none seems related to Keras (except for TensorFlow: AttributeError: ‘Tensor’ object has no attribute ‘log10’ which didn’t help)… I am making a sort of GAN (Generative Adversarial Networks). Here you can find the structure. I pretrained model_2, and model_3. The thing is I … Read more
