How to resolve the error in file_uploader in streamlit?


I am getting this error when trying to predict the image from loading it from streamlit file_uploader. The process is working fine when I try directly loading the image in ide. But the problem is arising with streamlit file_uploader. I canโ€™t figure in which file type the streamlit is uploading the file.

Steps to reproduce

Code snippet:

from tensorflow.keras.models import load_model
model = load_model('../streamlit/pages/sickmushroom_classifier.h5')

IMAGE_SIZE = (150,150)

class_names = ['oyster_blue','oyster_brown',
               'portobello_blue', 'portobello_brown', 'portobello_white',
               'winter_black', 'winter_blue', 'winter_white']

class_labels = {class_name:i for i, class_name in enumerate(class_names)}

number_classes = len(class_names)

def load_and_prep_image(filename, img_shape=150, scale=True):

    imge =
    imge =, channels=3)
    imge = tf.image.resize(imge, list(IMAGE_SIZE))
    if scale: 
        return imge/255.
        return imge 

upload= st.file_uploader('Insert image for classification', type=['png','jpg', 'jpeg'])
c1, c2= st.columns(2)
if upload is not None:
  img= np.asarray(im)
  image= cv2.resize(img, (150, 150))
  img= preprocess_input(image)
  img= np.expand_dims(img, 0)
  c1.header('Input Image')

#load weights of the trained model.
  img2 = load_and_prep_image(upload, scale=False)
  img_expanded = tf.expand_dims(img2, axis=0)
  pred_prob = model.predict(img_expanded)
  pred_class = class_names[pred_prob.argmax()]
  c2.subheader('Predicted class :')

Thank you for reading it. I hope this problem is solved.

What type of file are you uploading when you see this error?
