我正在编写一个客户端python文件,它使用flask框架并在docker机器中运行它。所以这需要一个输入文件并生成它的输出。 但它抛出错误,它无法转换为张量。
tf.app.flags.DEFINE_string('server', 'localhost:9000', 'PredictionService host:port')
FLAGS = tf.app.flags.FLAGS
app = Flask(__name__)
class mainSessRunning():
def __init__(self):
host, port = FLAGS.server.split(':')
channel = implementations.insecure_channel(host, int(port))
self.stub = prediction_service_pb2.beta_create_PredictionService_stub(channel)
self.request = predict_pb2.PredictRequest()
self.request.model_spec.name = 'modelX'
self.request.model_spec.signature_name = 'prediction'
def inference(self, val_x):
data = val_x
self.request.inputs['input'].CopyFrom(tf.contrib.util.make_tensor_proto(data))
result = self.stub.Predict(self.request, 5.0)
return result
run = mainSessRunning()
# Define a route for the default URL, which loads the form
@app.route('/pred', methods=['POST'])
def pred():
request_data = request.files['file']
result = run.inference(request_data)
rs = json_format.MessageToJson(result)
return jsonify({'result':rs})
错误说:
TypeError:无法转换类型的对象 (class'werkzeug.datastructures.File.Storage')张量。内容: (Filestorage:u'File.txt'('text / plain'))。考虑铸造元素 到支持的类型
此行产生错误:
self.request.inputs [ '输入']。具有copyfrom(tf.contrib.util.make_tensor_proto(数据))
