MUCH 痛苦和困惑之后,我终于让Swift从S3下载文件。呼...

我正在使用TransferManager ..

df = pd.DataFrame(np.random.randn(100, 100))
x = df[(df > 2).any(axis=1)]
print x._is_view
>>> True

# Prove that below we are referring to the exact same slice of the dataframe
assert (x.iloc[:len(x), 1] == x.iloc[:, 1]).all()

# Assign using equivalent notation to below
x.iloc[:len(x), 1] = 1
print x._is_view
>>> True

# Assign using slightly different syntax
x.iloc[:, 1] = 1
print x._is_view
>>> False

这在本地保存文件,我似乎无法将结果作为UIImage存储在数组中,而不在本地保存它。这将导致我的应用程序出现严重膨胀。如何将文件保存到数组而无需将其保存为lcoally?
