在水瓶中的网页上看不到图像
在水瓶中的网页上看不到图像
提问于 2020-03-17 08:45:01
我已经尝试了所有的可能性，但当我点击按钮，它没有显示我的图像，我从当地的电脑动态采取。它有3到4个不同Html的应用程序路由(其中一个是bs.html)。在此，我有两个模块:一个用于身体分割，另一个用于脑肿瘤检测。app.py
model = tf.keras.models.load_model("CNN1.model")
the_model = torch.load('cnn.pt')
app = Flask(__name__,instance_relative_config=True, static_url_path = "/static", static_folder = "static")
UPLOAD_FOLDER = './static'
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
def prepare(file): #image-processing for body segmentation
---------
---------
return sample_array
def transform(file): #image-processing for brain tumor
----------
----------
return img_t
@app.route('/')
def index():
# Main page
return render_template('RCnn.html')
@app.route('/body_seg')
def body_seg():
return render_template('bs1.html')
@app.route('/brain_t')
def brain_t():
return render_template('brain1.html')
@app.route('/body', methods=['POST','GET']) #to detect body segmentation parts
def body():
if request.method =='POST':
file1 = request.files['file']
if file1:
filename = secure_filename(file1.filename)
# task 1. let's get a clear path
path = os.path.join(app.config['UPLOAD_FOLDER'], filename)
path = os.path.abspath(path)
# task 2. make sure the folder exists
folder = os.path.dirname(path)
if not os.path.isdir(folder):
raise IOError('no such folder: %s' % folder)
file1.save(path)
abc=prepare(os.path.join(app.config['UPLOAD_FOLDER'],filename))
uploadimage=file1.filename
prediction = model.predict(abc)
return render_template('bs1.html',image=uploadimage, data=data2, data3=data3)
@app.route('/brain', methods=['POST','GET']) #module to detect brain tumor
def brain():
if request.method =='POST':
file1 = request.files['file']
if file1:
filename = secure_filename(file1.filename)
# task 1. let's get a clear path
path = os.path.join(app.config['UPLOAD_FOLDER'], filename)
path = os.path.abspath(path)
# task 2. make sure the folder exists
folder = os.path.dirname(path)
if not os.path.isdir(folder):
raise IOError('no such folder: %s' % folder)
file1.save(path)
#torch.save(model_conv,'cnn.pt')
the_model = torch.load('cnn.pt')
img_t = transform(os.path.join(app.config['UPLOAD_FOLDER'],filename))
uploadimage1=file1.filename
batch_t = torch.unsqueeze(img_t, 0)
out = the_model(batch_t)
return render_template('brain1.html',image1=uploadimage1,data=data4, data3=data5)
if __name__ == '__main__':
app.run(debug=True, use_reloader=False)bs.html

指定app.config['UPLOAD_FOLDER']的相对路径不是一个好主意，因为当前目录不是一个可靠的值。不过，您可以使用相对于python脚本的路径。就像这样：
app_dir = os.path.dirname(os.path.abspath(__file__))
app.config['UPLOAD_FOLDER'] = os.path.join(app_dir, 'static')现在，app.config中的路径将始终是脚本文件旁边的静态文件夹。
那就做你的事：
file = request.files['file']
if file:
filename = secure_filename(file.filename)
# task 1. let's get a clear path
path = os.path.join(app.config['UPLOAD_FOLDER'], filename)
path = os.path.abspath(path)
# task 2. make sure the folder exists
folder = os.path.dirname(path)
if not os.path.isdir(folder):
raise IOError('no such folder: %s' % folder)
file.save(path)
# ... then do template rendering...
return render_template(...)顺便说一下。使用file作为变量名是个坏主意。file是python中的内置类型。

当您呈现'bs.html‘的模板时，传入图像文件名；这是否应该是文件路径，即abc？
