我在 jupyter note 中提供数据路径时遇到一些问题

如何解决我在 jupyter note 中提供数据路径时遇到一些问题

我在使用 Jupyter Notebook 时遇到数据路径问题：

data_path='E:\7th Semester\FYP\mit-bih-arrhythmia-database-1.0.0\mit-bih-arrhythmia-database-1.0.0'

我遇到以下错误：

OSError                                   Traceback (most recent call last)
<ipython-input-9-22eb7ee6dcc7> in <module>
      1 for pt in pts:
      2     file = data_path + pt
----> 3     annotation = wfdb.rdann(file,'atr')
      4     sym = annotation.symbol
      5 

C:\ProgramData\Anaconda3\lib\site-packages\wfdb\io\annotation.py in rdann(record_name,extension,sampfrom,sampto,shift_samps,pn_dir,return_label_elements,summarize_labels)
   1625 
   1626     # Read the file in byte pairs
-> 1627     filebytes = load_byte_pairs(record_name,pn_dir)
   1628 
   1629     # Get Wfdb annotation fields from the file bytes

C:\ProgramData\Anaconda3\lib\site-packages\wfdb\io\annotation.py in load_byte_pairs(record_name,pn_dir)
   1748     # local file
   1749     if pn_dir is None:
-> 1750         with open(record_name + '.' + extension,'rb') as f:
   1751             filebytes = np.fromfile(f,'<u1').reshape([-1,2])
   1752     # PhysioNet file

OSError: [Errno 22] Invalid argument: 'E:\x07th Semester\\FYP\\mit-bih-arrhythmia-database-1.0.0\\mit-bih-arrhythmia-database-1.0.0100.atr'

解决方法

尝试使用双反斜杠（或原始字符串）：

<div>
  <form class="form1">
   <button class="button1">button1</button>
</form>
<form class="form2">
   <button class="button2">button2</button>
</form><div>

,

问题与你的路径有关 -

你可以使用python中可用的r-string

#### set data_path as below - 

data_path=r'E:\7th Semester\FYP\mit-bih-arrhythmia-database-1.0.0\mit-bih-arrhythmia-database-1.0.0'

注意 - 使用 r 时不要在末尾添加结束正斜杠
