Ask the code to run the error problem

[daysofchasingdream]

Hello, sorry to bother you. Your code has taught me a lot. When I ran your densecnn data, I found that the program reported the following error, which means that resample_freq does not exist.
（您好，打扰您了，您的代码让我学习到了很多东西，我在运行您的densecnn数据的时候，发现程序报错如下，意思指的是不存在resample_freq。）

In the part of your data preprocessing, I noticed that this resample_freq is outside the with. I would like to ask if this line of code should be inside the ‘with‘? Thank you for your answer, I wish you a happy life~
（在您的数据预处理部分，我注意到这个resample_freq是在with外面，想请问一下这行代码应该是在with里面吗？谢谢您的解答，祝您生活愉快~）

我在运行代码时，也出现了和你一样的问题，我觉得第二个hf应该放在with里面

我用这个代码处理TUSZ v2.0.3也有这个问题，但修改之后没有报错了，可以参考讨论一下：

 def resample_all(raw_edf_dir, save_dir):
    os.makedirs(save_dir, exist_ok=True)

    edf_files = []
    for path, _, files in os.walk(raw_edf_dir):
        for name in files:
            if name.endswith(".edf"):
                edf_files.append(os.path.join(path, name))

    failed_files = []
    for edf_fn in tqdm(edf_files, desc="Processing EDF files"):
        save_fn = os.path.join(save_dir, os.path.relpath(edf_fn, raw_edf_dir)).replace(".edf", ".h5")
        
        os.makedirs(os.path.dirname(save_fn), exist_ok=True)

        if os.path.exists(save_fn):
            continue

        try:
            with pyedflib.EdfReader(edf_fn) as f:
                orderedChannels = getOrderedChannels(
                    edf_fn, False, f.getSignalLabels(), INCLUDED_CHANNELS
                )
                signals = getEDFsignals(f)
                signal_array = np.array(signals[orderedChannels, :])
                sample_freq = f.getSampleFrequency(0)

                if sample_freq != FREQUENCY:
                    signal_array = resampleData(
                        signal_array,
                        to_freq=FREQUENCY,
                        window_size=int(signal_array.shape[1] / sample_freq),
                    )

                with h5py.File(save_fn, "w") as hf:
                    hf.create_dataset("resampled_signal", data=signal_array)
                    hf.create_dataset("resample_freq", data=FREQUENCY)

        except Exception as e:
            failed_files.append((edf_fn, str(e)))

    print(f"DONE. {len(failed_files)} files failed.")
    if failed_files:
        print("Failed files:")
        for file, error in failed_files:
            print(f"{file}: {error}")
