Hello, I am a new member. I have just started learning TensorFlow. I know about the basics, and I would like to move forward. I am having trouble downloading and installing the TensorFlow object detection A.P.I. for Python. I am following the steps listed on the official TensorFlow website, but nothing works. Every time I run the installation command, my system starts downloading the files and never finishes. It takes hours to complete the download of some files. I would appreciate any form of help.
