Tensorflow:V2
我在此视频https://www.youtube.com/watch?v=uabNEQlpGM8中使用了Tensorflow和docker服务,>
powershell中的代码:
docker pull tensorflow/serving mkdir tf_test cd .\tf_test\ ls git clone https://github.com/tensorflow/serving Set-Variable -Name "TESTDATA" -Value "$(pwd)/serving/tensorflow_serving/servables/tensorflow/testdata" docker run -t --rm -p 8501:8501 -v "$TESTDATA/saved_model_half_plus_two_cpu:/models/half_plus_two" -e MODEL_NAME=half_plus_two tensorflow/serving Get-Alias curl Remove-Item alias:curl curl -X POST http://localhost:8501/v1/models/half_plus_two:predict -d '{\"instances\": [1.0, 2.0, 5.0]}'
并且通过删除视频中提到的别名,我得到了请求的输出(在Powershell中]
curl -X POST http://localhost:8501/v1/models/half_plus_two:predict -d '{\"instances\": [1.0, 2.0, 5.0]}' >> { "predictions": [2.5, 3.0, 4.5 ] }
现在我想在python脚本中发出相同的API请求
# importing the requests library import requests import json # defining the api-endpoint API_ENDPOINT = "http://localhost:8501/v1/models/half_plus_two:predict" #curl -X POST http://localhost:8501/v1/models/half_plus_two:predict -d '{\"instances\": [1.0, 2.0, 5.0]}' # data to be sent to api data = {'instances':[1.0, 2.0, 5.0]} # sending post request and saving response as response object r = requests.post(url = API_ENDPOINT, data = data) # extracting response text pastebin_url = r.text print("The pastebin URL is:%s"%pastebin_url)
但是我收到以下错误
The pastebin URL is:{ "error": "JSON Parse error: Invalid value. at offset: 0" }
状态码= 400错误的请求
代码有什么问题?
OS:Window 10 Tensorflow:V2,我在此视频中使用了Tensorflow与docker服务https://www.youtube.com/watch?v=uabNEQlpGM8 powershell中的代码:docker pull tensorflow / serving mkdir ...
尝试requests.post(url = API_ENDPOINT, data = json.dumps(data))
