CNN Cannot Identify Image File - tensorflow

Question

I have made a simple CNN to recognize three types of fish. I am trying to use CNN to classify the image that was not included in training or validation sets. The image is grunts-saltwater.jpg and is on Gdrive. Here is the code for predicting on existing CNN model:
grunts_url = "https://drive.google.com/file/d/1zuA6T_0a9mOUvNWHQ1OACPLaZMCtbIZd/view?usp=sharing"
grunts_path = tf.keras.utils.get_file('grunts-saltwater', origin=grunts_url)
img = keras.preprocessing.image.load_img(
grunts_path, target_size=(img_height, img_width))
img_array = keras.preprocessing.image.img_to_array(img)
img_array = tf.expand_dims(img_array, 0) # Create a batch
predictions = model.predict(img_array)
score = tf.nn.softmax(predictions[0])
print(
"This image most likely belongs to {} with a {:.2f} percent confidence."
.format(class_names[np.argmax(score)], 100 * np.max(score))
)
However, I get the following error:
Downloading data from https://drive.google.com/file/d/1zuA6T_0a9mOUvNWHQ1OACPLaZMCtbIZd/view?usp=sharing

Can you help with the issue, please? Thanks.

Answer 1

It is because the google drive link of the image is now a downloadable line rather it is a view link. If it is shared then you can convert it into a downloadable link such that http clients can download them.
To covert to downloadable line
Your shared image ID is 1zuA6T_0a9mOUvNWHQ1OACPLaZMCtbIZd so use the link "https://docs.google.com/uc?export=download&id=1zuA6T_0a9mOUvNWHQ1OACPLaZMCtbIZd"
Fixed code:
grunts_url = "https://docs.google.com/uc?export=download&id=1zuA6T_0a9mOUvNWHQ1OACPLaZMCtbIZd"
grunts_path = tf.keras.utils.get_file('grunts-saltwater', origin=grunts_url)
img = keras.preprocessing.image.load_img(grunts_path, target_size=(100, 100))

I managed to resolve the issue. I do not think I was referring to source URL correctly. Here is an example that worked.
gruntfish_url = "https://upload.wikimedia.org/wikipedia/commons/5/54/Blue_Stripe_Grunt._Haemulon_sciurus.jpg"
gruntfish_path = tf.keras.utils.get_file('Grunt.', origin=gruntfish_url)
