flaskapp.pyflaskapp.wsgi
flaskapp.pyのコードは次のとおりです：
import sys
import os
import shutil
import time
import traceback
from flask import Flask, request, jsonify
app = Flask(__name__)
@app.route('/predict')
def predict():
from sklearn.externals import joblib
import numpy as np
clf = joblib.load("flaskapp/models/saved_model.pkl")
print 'model loaded'
if clf:
try:
prediction = list(clf.predict(np.array([['0', '100', '164', '150', '1']])))
return jsonify({'prediction': prediction})
except Exception, e:
return "ERROR" + e
else:
print os.getcwd()
return 'no model here'
if __name__ == '__main__':
from sklearn.externals import joblib
import numpy as np
print "Imports Done"
app.run(DEBUG=True)
