When I try the code with the original data (data.dat) as you suggested, I get the following error : Memory Error --> (error.png), how can i overcome this problem, thank you so much in advance.

I want to cluster them using Birch clustering algorithm.
Does this method have 'precomputed' option.
No it doesn't, see http://scikit-learn.org/stable/modules/generated/sklearn. so you would need to provide it with the original features matrix (not the precomputed distance matrix). Since your dataset is fairly small, there is no reason in precomputing it anyway.cluster.Birch.html
I needed train an SVM on the centroids of the microclusters so
*How can i get the centroids of the microclusters?*
By "microclusters" do you mean sub-clusters? If you are interested in the leaves subclusters see the Birch.subcluster_centers_ parameter.
Otherwise if you want all the centroids in the hierarchy of subclusters, you can browse the hierarchical tree via the Birch.root_ attribute then look at _CFSubcluster.centroid_ for each subcluster.
Hope this helps,
