Can anyone help me with the below code as it is working fine without flask in local system but not with FLASK? : <p>Code is running fine with local system but I'm getting the following error whenever I try to submit data to my Flask form:</p>

<p>Error: Method Not Allowed The method is not allowed for the requested URL.</p>

<p>Relevant parts of my code are as follows:</p>

<pre><code>pytesseract.pytesseract.tesseract_cmd = 'C:\\Users\\Abhi\\AppData\\Local\\Programs\\Python\\Python37-32\\Lib\\site-packages\\pytesseract\\Tesseract-OCR\\tesseract.exe'

PDFTOPPMPATH = r"C:\Users\Abhi\Downloads\poppler-0.68.0_x86\poppler-0.68.0\bin\pdftoppm.exe"
PDFFILE = "C:\\Users\\Abhi\\rep.pdf"
subprocess.Popen('"%s" -png "%s" out' % (PDFTOPPMPATH, PDFFILE))

app = Flask(__name__)

@app.route('/', methods=['POST'])
def predict():

    im = Image.open("out-2.png")
    rgb_im = im.convert('RGB')
    rgb_im.save('m.jpg')

    im = Image.open("m.jpg")
    text1 = pytesseract.image_to_string(im, lang = 'eng')

    with open("report.txt","w") as f:
        f.write(text1)


    para = ["Emissivity","Refl. temp.","Distance","Relative humidity","Atmospheric temperature","Transmission"]

    f=open('report.txt')
    lines=f.readlines()
