python - 如何修复 Jupyter Notebook pandas 错误(OSError : [WinError 193] %1 is not a valid Win32 application)

Question

我目前正在机器学习类(class)中从事 Yelp 回归项目。

该项目要求我打开 Jupyter 笔记本并将 pandas 导入为 py。

我使用 Anaconda 导航器打开 Jupyter 笔记本。我得到以下信息:

(OSError: [WinError 193] %1 is not a valid Win32 application)

当我尝试为我的代码导入 pandas 时。完整消息:

OSError Traceback (most recent call last)

businesses = pd.read_json('yelp_business.json', lines = True)

5 users = pd.read_json('yelp_user.json', lines = True)

我已经尝试卸载和安装 python、anaconda 和 pandas。

您可能在 32 位系统上下载了 64 位 pandas。卸载并重新安装，但要特别注意这一点。
