Roboflow suggested, Yolov5-obb in Google Colab, will no longer build executables

Have been using the Roboflow directions for Google Colab on YOLOv5-obb for a number of weeks, successfully. Today, I notice that this line is now failing:
!pip3 install torch==1.10.1+cu113 torchvision==0.11.2+cu113 torchaudio==0.10.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html

It returns:
Looking in indexes: Simple index , …
Looking in links: … (have to remove the links to get this to post)
ERROR: Could not find a version that satisfies the requirement torch==1.10.1+cu113 (from versions: 1.11.0, 1.11.0+cu113, 1.12.0, 1.12.0+cu113, 1.12.1, 1.12.1+cu113, 1.13.0, 1.13.1, 2.0.0)
ERROR: No matching distribution found for torch==1.10.1+cu113

Any idea where to find a version of torch that satisfies the needed cuda requirement?
