                  #     numpy, the `updateMask` parameter would include the following two

                  #     "config.softwareConfig.pypiPackages.numpy". The included patch
                  #     environment would specify the scikit-learn version as follows:
                  #
                  #         {

                  #                 "scikit-learn":"==0.19.0"

                  #         }
                  #
                  #     Note that in the above example, any existing PyPI packages
                  #     other than scikit-learn and numpy will be unaffected.
                  #
                  #     Only one update type may be included in a single request's `updateMask`.
                  #     For example, one cannot update both the PyPI packages and
                  #     labels in the same request. However, it is possible to update multiple
                  #     members of a map field simultaneously in the same request. For example,
                  #     to set the labels "label1" and "label2" while clearing "label3" (assuming
                  #     it already exists), one can
                  #     provide the paths "labels.label1", "labels.label2", and "labels.label3"
                  #     and populate the patch environment as follows:
                  #
                  #         {
                  #           "labels":{
                  #             "label1":"new-label1-value"
                  #             "label2":"new-label2-value"
                  #           }
                  #         }
                  #
                  #     Note that in the above example, any existing labels that are not
                  #     included in the `updateMask` will be unaffected.
                  #
                  #     It is also possible to replace an entire map field by providing the
                  #     map field's path in the `updateMask`. The new value of the field will
                  #     be that which is provided in the patch environment. For example, to
                  #     delete all pre-existing user-specified PyPI packages and
                  #     install botocore at version 1.7.14, the `updateMask` would contain
                  #     the path "config.softwareConfig.pypiPackages", and
                  #     the patch environment would be the following:
                  #
                  #         {
                  #           "config":{
