-{
-     "HostConfig": {
-         "DeviceRequests": 
-         [
-             {
-                 "Count": -1,
-                 "Capabilities": [
-                     [
-                         "gpu"
-                     ]
-                 ]
-             }
-         ]
-     }
- }
+{"HostConfig": {"DeviceRequests": [{"Count": -1,"Capabilities": [["gpu"]]}]}}
 ```
