You could specify it similarly to this simple example in the scikit-learn
documentation (here: to avoid tuning gamma for a linear SVM):
http://scikit-learn.org/stable/modules/grid_search.html#exhaustive-grid-search
<http://scikit-learn.org/stable/modules/grid_search.html#exhaustive-grid-search>
param_grid = [
{'C': [1, 10, 100, 1000], 'kernel': ['linear']},
{'C': [1, 10, 100, 1000], 'gamma': [0.001, 0.0001], 'kernel': ['rbf']},
]
Best,
Sebastian
