出现错误

caffe: TypeError: _open() got an unexpected keyword argument ‘as_grey‘
 “as_grey” 实际应当修改为 “as_gray”，原因是 scikit-image 的 0.17.2 版本修改了参数名称

ValueError: Object arrays cannot be loaded when allow_pickle=False
自Numpy 1.16.3版本发行之后，函数 numpy.load() 和 numpy.lib.format.read_array() 采用allow_pickle关键字，现在默认为False以响
pip install numpy=1.16.2

Note: Currently only jpeg images are supported.

classify_nsfw.py accepts some optional parameters you may want to play around with:

usage: classify_nsfw.py [-h] -m MODEL_WEIGHTS [-l {yahoo,tensorflow}]
                        [-t {tensor,base64_jpeg}]
                        input_jpeg_file

positional arguments:
  input_file            Path to the input image. Only jpeg images are
                        supported.

optional arguments:
  -h, --help            show this help message and exit
  -m MODEL_WEIGHTS, --model_weights MODEL_WEIGHTS
                        Path to trained model weights file
  -l {yahoo,tensorflow}, --image_loader {yahoo,tensorflow}
                        image loading mechanism
  -i {tensor,base64_jpeg}, --input_type {tensor,base64_jpeg}
                        input type

-l/–image-loader

The classification tool supports two different image loading mechanisms.

• yahoo (default) replicates yahoo’s original image loading and preprocessing. Use this option if you want the same
  results as with the original implementation
• tensorflow is an image loader which uses tensorflow exclusively (no dependencies on PIL, skimage, etc.). Tries
  to replicate the image loading mechanism used by the original caffe implementation, differs a bit though due to
  different jpeg and resizing implementations.
  See this issue for details.

Note: Classification results may vary depending on the selected image loader!

-i/–input_type

Determines if the model internally uses a float tensor (tensor - [None, 224, 224, 3] - default) or a base64 encoded
string tensor (base64_jpeg - [None, ]) as input. If base64_jpeg is used, then the tensorflow image loader will
be used, regardless of the -l/–image-loader argument.

Tools

The tools folder contains some utility scripts to test the model.

create_predict_request.py

Takes an input image and generates a json file suitable for prediction requests to a Open NSFW Model deployed
with Google Cloud ML Engine (gcloud ml-engine predict)
or tensorflow-serving.

export_savedmodel.py

Exports the model using the tensorflow serving export api (SavedModel). The export can be used to deploy the model
on Google Cloud ML Engine
, Tensorflow Serving or on mobile (haven’t tried that one yet).

export_tflite.py

Exports the model in TFLite format. Use this one if you want to run inference on
mobile or IoT devices. Please note that the base64_jpeg input type does not work with TFLite since the standard
runtime lacks a number of required tensorflow operations.

export_graph.py

Exports the tensorflow graph and checkpoint. Freezes and optimizes the graph per default for improved inference and
deployment usage (e.g. Android, iOS, etc.). Import the graph with tf.import_graph_def.
