Another indentation bug in train_model.py

[leonsery]

Identation mistake. Instead of:

# randomly select a few testing characters
for i in np.random.choice(np.arange(0, len(testY)), size=(49,)):
    # classify the character
    probs = model.predict(testX[np.newaxis, i])
prediction = probs.argmax(axis=1)
label = labelNames[prediction[0]]

# extract the image from the test data and initialize the text
# label color as green (correct)
image = (testX[i] * 255).astype("uint8")
color = (0, 255, 0)

# otherwise, the class label prediction is incorrect
if prediction[0] != np.argmax(testY[i]):
    color = (0, 0, 255)

# merge the channels into one image, resize the image from 32x32
# to 96x96 so we can better see it and then draw the predicted
# label on the image
image = cv2.merge([image] * 3)
image = cv2.resize(image, (96, 96), interpolation=cv2.INTER_LINEAR)
cv2.putText(image, label, (5, 20), cv2.FONT_HERSHEY_SIMPLEX, 0.75,
color, 2)

# add the image to our list of output images
images.append(image)

It should be:

# randomly select a few testing characters
for i in np.random.choice(np.arange(0, len(testY)), size=(49,)):
    # classify the character
    probs = model.predict(testX[np.newaxis, i])
    prediction = probs.argmax(axis=1)
    label = labelNames[prediction[0]]

    # extract the image from the test data and initialize the text
    # label color as green (correct)
    image = (testX[i] * 255).astype("uint8")
    color = (0, 255, 0)

    # otherwise, the class label prediction is incorrect
    if prediction[0] != np.argmax(testY[i]):
        color = (0, 0, 255)

    # merge the channels into one image, resize the image from 32x32
    # to 96x96 so we can better see it and then draw the predicted
    # label on the image
    image = cv2.merge([image] * 3)
    image = cv2.resize(image, (96, 96), interpolation=cv2.INTER_LINEAR)
    cv2.putText(image, label, (5, 20), cv2.FONT_HERSHEY_SIMPLEX, 0.75,
    color, 2)

    # add the image to our list of output images
    images.append(image)
