[英]Image input for Python Tensorflow model in CoreML
I'm implementing a simple image classification model with tensor flow (python). 我正在使用张量流(python)实现一个简单的图像分类模型。
Here's my image preprocessing: 这是我的图像预处理:
import glob
for filename in glob.glob('/Volumes/G-DRIVE mobile USB-C/traan/*.jpeg'): #assuming jpeg
im=Image.open(filename)
im = im.resize((150,120), Image.ANTIALIAS)
print(im.size)
training_images.append(im)
And here's my very simple model: 这是我非常简单的模型:
model = keras.Sequential([
keras.layers.Flatten(input_shape=(120, 150, 3)),
keras.layers.Dense(512, activation=tf.nn.relu),
keras.layers.Dense(256, activation=tf.nn.relu),
keras.layers.Dense(128, activation=tf.nn.relu),
keras.layers.Dense(10, activation=tf.nn.softmax)
])
I want to load this model to CoreML something like this, 我想将此模型加载到CoreML中,
import coremltools
modelCoreML = coremltools.converters.tensorflow.convert(model, input_feature, output_feature)
modelCoreML.save("Model.mlmodel")
But how do I do this where I can input an image, and not a numpy stack? 但是如何在可以输入图像而不是numpy堆栈的位置执行此操作? Should I process the image and turn it into the right format in the app itself, then put it in the model? 我应该在应用程序本身中处理图像并将其转换为正确的格式,然后将其放入模型中吗? How would I do this? 我该怎么做?
You need to supply the image_input_names
argument to coremltools.converters.keras.convert()
so that coremltools knows which inputs should be treated as images. 您需要向coremltools.converters.keras.convert()
提供image_input_names
参数,以便coremltools知道应将哪些输入视为图像。 This is explained in the documentation . 文档中对此进行了说明 。
