Question

我尝试读取我已读写的csv文件，并使用Win10中Visual Code.下的pandas对数据帧进行了读写访问。

df1 = pd.read_csv("C:\\Users\\me\\Desktop\\Python\\Analytics\\in\\test_DS.csv", sep=';', header = None)

df1 = pd.read_csv(r"C:\Users\me\Desktop\Python\Analytics\in\test_DS.csv", sep=';', header = None)

df1 = pd.read_csv(r"C:/Users/me/Desktop/Python/Analytics/in/test_DS.csv", sep=';', header = None)

但是我仍然得到Error：无法打开parsers.pyx中找不到的C:/Users/me/Desktop/Python/Pandas/_libs/parsers.pyx.文件

有人可以告诉我我在做什么错吗？

******************跟踪为了实现回溯，我实现了：

except Exception:
        print("Exception in user code:")
        print("-"*60)
        traceback.print_exc(file=sys.stdout)
        print("-"*60)

我知道了

Exception in user code:

During handling of the above exception, another exception occurred:

我今天也遇到了同样的问题，重新安装pandas和numpy并没有帮助。然后我意识到我的分隔符是错误的。解决该问题的方法已解决。值得检查吗？

此外，您的回溯使文件看起来好像已损坏；也许还要在此处发布文件顶部以进行调试。
