Serialize a dictionary containing pandas data-frames (Python)

I have a dict containing several pandas Dataframe (identified by keys) , any suggestion to effectively serialize (and cleanly load) it . Here is the structure (a pprint display output ). Each of dict['method_x_']['meas_x_'] is a pandas Dataframe. The goal is to save the dataframes for a further plotting with some specific plotting options.

{'method1':

{'meas1':

                          config1   config2
                   0      0.193647  0.204673
                   1      0.251833  0.284560
                   2      0.227573  0.220327,

'meas2':   

                          config1   config2
                   0      0.172787  0.147287
                   1      0.061560  0.094000
                   2      0.045133  0.034760,

'method2':

{ 'meas1':

                          congif1   config2
                   0      0.193647  0.204673
                   1      0.251833  0.284560
                   2      0.227573  0.220327,

'meas2':

                          config1   config2
                   0      0.172787  0.147287
                   1      0.061560  0.094000
                   2      0.045133  0.034760}}
