错误消息：h5py.h5py_warnings.H5pyDeprecationWarning：dataset.value 已被弃用。使用 dataset[()] 代替

Question

我正在尝试运行mbin进行甲基化分析。但是得到错误消息：h5py.h5py_warnings.H5pyDeprecationWarning: dataset.value has been deprecated. Use dataset[()] instead. 多次尝试，同时尝试使用 buildcontrols 提取控制 IPD。
环境：

• mbin 版本：1.1.1
• Python版本：2.7.12
• 操作系统：centOS
• 在 virtualenv 下运行

我还以为是版本问题。我尝试过的：我在同时使用 python 3 和 2 的服务器上尝试过。并指定 virtualenv 使用 python 2 作为解释器。mbin 已成功安装，但 buidlcontrols 没有。

我检查了python版本：

(virtualenv_for_mbin) [yx@localhost virtualenv_for_mbin]$ python -V
Python 3.6.5 :: Anaconda, Inc.

所以，我立即尝试运行一个新的 virtualenv。

[yx@localhost Software]$ mkdir venv_tmp
[yx@localhost Software]$ cd venv_tmp/
[yx@localhost venv_tmp]$ virtualenv --python=/usr/local/bin/python2.7 .
Running virtualenv with interpreter /usr/local/bin/python2.7
New python executable in /data2/Software/venv_tmp/bin/python2.7

done.
[yx@localhost venv_tmp]$ . bin/activate
(venv_tmp) [yx@localhost venv_tmp]$ python -V
Python 3.6.5 :: Anaconda, Inc.

然后，我转向另一台服务器......只安装了python 2.7。

仍然收到相同的错误消息。我在这里希望有人可以帮助我。多谢。

正如您所说，您需要使用新的方法来获取标量值。该.value语法仍然有效，但谁愿意看到在Jupyter粉红色的警告？

该消息不是很直观，语法也不是。所以我会在这里拼出来 - 你有一个名为 f 的 d5py.File：

>>> f = h5py.File('temp.h5')
>>> f['path/to/scalar'] = 5
>>> f['path/to/scalar'].value
(...)\site-packages\h5py\_hl\dataset.py:313: H5pyDeprecationWarning: dataset.value has been deprecated. Use dataset[()] instead. "Use dataset[()] instead.", H5pyDeprecationWarning)
5

“改用数据集[()]”的字面意思是“使用索引 ( __getitem__) 运算符，并传递给它一个空的tuple( ())。所以最后一行应该是：

>>> f['path/to/scalar'][()]
5

如果你觉得这有点奇怪，异国情调的符号，我只能感同身受。

但它是有道理的 -numpy.shape标量值实际上是().
