打开文件困难

Question

我将goog.npz文件保存在下面建议的目录中，而不是将其保存在这里：

file_path ='C：/ Users /.../ goog.npz'

，然后用r（在下面）替换为读取存储位置文件的内容。感谢您的帮助！

# Load a numpy record array from yahoo csv data with fields date, open, close,
# volume, adj_close from the mpl-data/example directory. The record array
# stores the date as an np.datetime64 with a day unit ('D') in the date column.

with cbook.get_sample_data('goog.npz') as datafile:
    r = np.load(datafile)['price_data'].view(np.recarray)

Answer 1

只需使用get_sample_data方法指定文件的整个路径：

with cbook.get_sample_data('C:Users/.../goog.npz') as datafile:
    r = np.load(datafile)['price_data'].view(np.recarray)
