如何覆盖npy文件并将其保存在目录中?

Question

我试图将numpy文件保存在特定目录并覆盖它。我该怎么做呢?

path = os.path.join(data_path, created_folder, 'testone')
with open('{}.npy'.format('testone'), 'ab') as f:
np.save(f, mydata)

Answer 1

您的代码打开了附加的文件，但您没有给它定义的正确路径。要覆盖它，使用模式w，如下所示:

path = os.path.join(data_path, created_folder, 'testone')
with open('{}.npy'.format(path), 'wb') as f:
np.save(f, mydata)
