TypeError: must be str, not numpy.int64

This should be working as i have seen it work on anothers however this is not working for me. I am doing a test/train model and trying to train the image

This is all that i have tried. Data saved on google drive

train_image = []
for i in tqdm(range(train.shape[0])):
    img = image.load_img('/content/drive/My Drive/Colab Notebooks/data/train/'+train['file_id'][i], target_size=(128,173,1), color_mode='grayscale')
    img = image.img_to_array(img)
    img = img/255
    train_image.append(img)
x_train = np.array(train_image)

      5     img = img/255

TypeError: must be str, not numpy.int64

Solution

Check whether the parameters passed in load_img and img_to_array is correct or not. I had the same error with my code. It was because I was calling a method to get a particular parameter for creating the path which returned a character (typing error) and affected it.
