{"library":"Sklearn","prompt":"Problem:\n\nI have a data which include dates in sorted order.\n\nI would like to split the given data to train and test set. However, I must to split the data in a way that the test have to be newer than the train set.\n\nPlease look at the given example:\n\nLet's assume that we have data by dates:\n\n1, 2, 3, ..., n.\n\nThe numbers from 1 to n represents the days.\n\nI would like to split it to 20% from the data to be train set and 80% of the data to be test set.\n\nGood results:\n\n1) train set = 1, 2, 3, ..., 20\n\n   test set = 21, ..., 100\n\n\n2) train set = 101, 102, ... 120\n\n    test set = 121, ... 200\nMy code:\n\ntrain_size = 0.2\ntrain_dataframe, test_dataframe = cross_validation.train_test_split(features_dataframe, train_size=train_size)\n\ntrain_dataframe = train_dataframe.sort([\"date\"])\ntest_dataframe = test_dataframe.sort([\"date\"])\nDoes not work for me!\n\nAny suggestions?\n\nA:\n\n<code>\nimport numpy as np\nimport pandas as pd\nfrom sklearn.model_selection import train_test_split\nfeatures_dataframe = load_data()\n</code>\ntrain_dataframe, test_dataframe = ... # put solution in these variables\nBEGIN SOLUTION\n<code>\n"}
