TAO Toolkit 4.0 Google colab DataSet download links issue

I am running the YOLO 3 Google colab work book and I am having an issue downloading the DATA SET.
I have retrived the DAT Set links from my e-mail and put them in the Colab script but I am getting a syntax error.
I have put the download links into my browser and it works but the script in the Colab workbook says there is a syntax error.

import os

!mkdir -p $DATA_DIR

os.environ[“URL_IMAGES”]= https://urldefense.com/v3/__https://s3.eu-central-1.amazonaws.com/avg-kitti/data_object_image_2.zip__;!!AWL9ZJ8!LrBzKGNXJ6O2OcSnkkMJoIGOcvrwxGoe8FjNY9vEjzF7n_kWWvOyl-8afGyjsaSAZ5hG8bMdDMmmXQ$

!if [ ! -f $DATA_DIR/data_object_image_2.zip ]; then wget $URL_IMAGES -O $DATA_DIR/data_object_image_2.zip; else echo “image archive already downloaded”; fi

os.environ[“URL_LABELS”]= https://urldefense.com/v3/__https://s3.eu-central-1.amazonaws.com/avg-kitti/data_object_label_2.zip__;!!AWL9ZJ8!PNbax0sC4KLreQXdzQ70EwsIdeklr-g15MW9n_ig5xK8BxhOzXWrgvQD-4HztOyP1sGIghn-v1MOxw$

!if [ ! -f $DATA_DIR/data_object_label_2.zip ]; then wget $URL_LABELS -O $DATA_DIR/data_object_label_2.zip; else echo “label archive already downloaded”; fi

Here is error:

  File "<ipython-input-5-f46475096188>", line 3

 SyntaxError: invalid syntax

Adding quotation mark for the URL?

That worked.
By the way the Google Colab option is way cool.
