[英]expected axis -1 of input shape to have value 28, but received input with shape (None, 28, 28, 5)
[英]Tensorflow gives error when predicting: expected axis -1 of input shape to have value 784 but received input with shape [None, 28]
當我使用 Python 在 TensorFlow 中使用神經網絡進行預測時,出現以下錯誤: ValueError: Input 0 of layer dense is incompatible with the layer: expected axis -1 of input shape to have value 784 but received input with shape [None, 28]
。
我正在嘗試按照 Tensorflow 網站上的教程來訓練神經網絡來對服裝進行分類。 我編寫了以下代碼:
import tensorflow as tf
from tensorflow import keras
import matplotlib.pyplot as plt
import numpy as np
from skimage import color, io
print(tf.__version__)
data = keras.datasets.fashion_mnist
(train_images, train_labels), (test_images, test_labels) = data.load_data()
class_names = ['T-shirt/top', 'Trouser', 'Pullover', 'Dress', 'Coat',
'Sandal', 'Shirt', 'Sneaker', 'Bag', 'Ankle boot']
train_images = train_images / 255
test_images = test_images / 255
model = keras.Sequential([
keras.layers.Flatten(input_shape=(28, 28)),
keras.layers.Dense(128, activation="relu"),
keras.layers.Dense(10, activation="softmax")
])
model.compile(
optimizer="adam",
loss="sparse_categorical_crossentropy",
metrics=["accuracy"]
)
model.fit(train_images, train_labels, epochs=20)
print(type(test_images))
images = [test_images[0]]
predictions = model.predict(images)
print(class_names[np.argmax(predictions[0])])
非常感謝任何幫助,TIA。
為了社區的利益,來自評論部分。
通過將model.predict(images)
更改為以下model.predict(images)
行已經解決了這個問題。
model.predict(np.expand_dims(test_images[0],0))
