.. ipython:: python :suppress: import numpy as np np.set_printoptions(precision=4, suppress=True) import pandas as pd pd.options.display.max_rows=8 Thread-safety ------------- As of pandas 0.11, pandas is not 100% thread safe. The known issues relate to the ``DataFrame.copy`` method. If you are doing a lot of copying of DataFrame objects shared among threads, we recommend holding locks inside the threads where the data copying occurs. See `this link `__ for more information.
