【问题描述】：

我想将尺寸为 (3960, 225) 的 X (ndarray) 保存在 excel 文件 (.xlsx) 中。在 X 中，我有一些缺失值 (nan)。我为它做了一个代码。但是，我得到了错误。

代码如下：

workbook = xlsxwriter.Workbook('arrays.xlsx')
    worksheet = workbook.add_worksheet()
    row = 0
    for col, data in enumerate(X):
        worksheet.write_column(row, col, data)
    workbook.close()
     df = pd.DataFrame(X)
## save to xlsx file
     filepath = 'my_excel_file.xlsx'
      df.to_excel(filepath, index=False)

这是回溯：

Traceback (most recent call last):
  File "C:\Program Files\JetBrains\PyCharm 2020.2.1\plugins\python\helpers\pydev\pydevd.py", line 1448, in _exec

    error = self._write(row, col, token, cell_format)
  File "C:\Users\Nafees Ahmed\AppData\Local\Programs\Python\Python38\lib\site-packages\xlsxwriter\worksheet.py", line 481, in _write
    return self._write_number(row, col, *args)

    raise TypeError(
TypeError: NAN/INF not supported in write_number() without 'nan_inf_to_errors' Workbook() option
 

也许是因为 nan（缺失）值。有没有简单的方法来处理这个错误？

【参考方案1】：

用零填充NaN 值，并不能解决问题，如果你想将NaN 值保持为NaN，你应该跳过这样的填充值：

row = 0
for col, data in enumerate(X):
    try:
        worksheet.write_column(row, col, data)
    except:
        pass

【参考方案2】：

你可以使用pandas的@​​987654321@方法。

df.fillna(0) 会将所有NaN 替换为0.0

【参考方案3】：

我使用以下代码填写了非：

X[np.isnan(X)] = 0.;
