TypeError: expected str, bytes or os.PathLike object, not JpegImageFile (or PngImageFile) in Django

Question

When I am uploading a picture to check a picture according to tensorflow h5 model, I am loading the image using load_model of tensorflow.keras.models but it is not accepting. For JPG, it is showing TypeError: expected str, bytes or os.PathLike object, not JpegImageFile and for PNG, it is showing as TypeError: expected str, bytes or os.PathLike object, not PngImageFile. What to do now?

I tried the code with raw python but it worked nicely.

Code:

#views.py

import numpy as np
from tensorflow.keras.models import load_model
from tensorflow.keras.preprocessing import image

pic = request.FILES['image']
img = Image.open(pic)
detection=load_model(os.path.join(settings.BASE_DIR,'static/auto_chloro_model.h5'))
test_img=image.load_img(img,target_size=(48,48))
test_img=image.img_to_array(test_img)
test_img=np.expand_dims(test_img,axis=0) 
result=detection.predict(test_img)
a=result.argmax()
print(a)

#models.py

class images(models.Model):
   img_main = models.ImageField(upload_to="images_api", default="") 

   def __str__(self):
        return self.product_name

#forms.py

class imageForm(forms.ModelForm):
    image = forms.ImageField()
  
    class Meta:
        model = images
        fields = ['image']

Traceback:

Answer 1

The load_img function expects path to the image, not PIL image format.

So instead of

img = Image.open(pic)
test_img=image.load_img(img,target_size=(48,48))

You can save the image, and then get url/path to image and then give path to image.load_img using :

from tensorflow.keras.preprocessing import image
from django.core.files.storage import default_storage


# test_img = image.load_img('/path/to/image.jpg', target_size = (48, 48))
file_name = "pic.jpg"   # The file name with which it saves
file = default_storage.save(file_name, f)
file_url = default_storage.url(file)
test_img = image.load_img(file_url, target_size=(48, 48))

This solved my problem.

pic = request.FILES['image']
img_new = images(img_main= pic)
img_new.save()
detection=load_model(os.path.join(settings.BASE_DIR,'staticfiles/auto_chloro_model.h5'))
test_img=image.load_img(img_new.img_main.path,target_size=(48,48))
test_img=image.img_to_array(test_img)
test_img=np.expand_dims(test_img,axis=0) 
result=detection.predict(test_img)
a=result.argmax()
