I am using python 3.6 and Keras (2.0.9) over Tensorflow
trying to download trained models of resnet50 but encounter the following error: Exception: URL fetch failure on https://github.com/fchollet/deep-learning-models/releases/download/v0.2/resnet50_weights_tf_dim_ordering_tf_kernels.h5: None -- [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)
the following is the code used:
from keras.applications.resnet50 import ResNet50
from keras.preprocessing import image
from keras.applications.resnet50 import preprocess_input, decode_predictions
import numpy as np
model = ResNet50(weights='imagenet')
img_path = 'elephant.jpg'
img = image.load_img(img_path, target_size=(224, 224))
x = image.img_to_array(img)
x = np.expand_dims(x, axis=0)
x = preprocess_input(x)
model.summary()
preds = model.predict(x)
print('Predicted:', decode_predictions(preds, top=3)[0])
You can consider this.
I also use the SSL module before downloading the data set. It solved this problem!
Like this:
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
Just ran into the same issue. I found the answer here: Mac OSX python ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:749)
Browse to Applications/Python 3.6 folder and double-click Install Certificates.command
I tested it on Mac and it worked.
Combining either or both the @Roman Mirochnik and @sos418 method should work i.e.
Browse to Applications/Python 3.x
folder and double-click Install Certificates.command
Add to code:
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
