- * Fix a memory leak with shared variable(we kept a pointor to the original value)
- * The key in our cache now store the hash of constant and not the constant value itself. This is significat for big constant.
- * theano-cache list list key file bigger then 1M
- * theano-cache list print an histograme of the number of key per compiled module
- * theano-cache list print the number of compiled module per op class
+ * Fixed a memory leak with shared variable (we kept a pointer to the original value)
+ * The keys in our cache now store the hash of constants and not the constant values themselves. This is significantly more efficient for big constant arrays.
+ * 'theano-cache list' lists key files bigger than 1M
