Hello I'm trying to build a simple api to receive an image and return some inference values. My filesystem is the following:
Mask_RCNN
|-MaskDetector.py
|-FireDetector(class)
fire_app
|-server.py
|-saved_img
If I open python console and run this:
import sys
sys.path.insert(0, '../Mask_RCNN')
new FireDetector.FireDetector('../trained_weights')
fire_detector.detect('/home/fctmasterthesis/fire_app/saved_img/image7.jpg')
It returns the expected result of inference:
({'rois': array([[ 238, 170, 988, 1359], (...)
But if I run it inside Flask server.py like this:
from flask import Flask
from flask import render_template
from flask import request, flash, redirect
from werkzeug.utils import secure_filename
import os
import sys
sys.path.insert(0, '../Mask_RCNN')
from MaskDetector import FireDetector
fire_detector = FireDetector('../trained_weights')
UPLOAD_FOLDER = 'saved_img'
ALLOWED_EXTENSIONS = set(['png', 'jpg', 'jpeg'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
def allowed_file(filename):
return '.' in filename and \
filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS
@app.route('/',methods=['GET', 'POST'])
def hello():
if request.method == 'POST':
if 'fire_image' not in request.files:
flash('No file part')
return redirect(request.url)
file = request.files['fire_image']
if file.filename == '':
flash('No selected file')
if file and allowed_file(file.filename):
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
return fire_detector.detect('/home/fctmasterthesis/fire_app/saved_img/'+'/'+filename)
return render_template('upload.html')
app.run(host='0.0.0.0',port='80')
While running It gives a code 500 with the following error:
ValueError: Tensor Tensor("mrcnn_detection/Reshape_1:0", shape=(1, 100, 6), dtype=float32) is not an element of this graph.
