使用 Pandas read_csv 讀取 CSV 文件時出現 parsers.pyx 錯誤

Question

我嘗試在Visual Code.的Win10下使用 pandas 將我具有讀寫權限的 csv 文件讀取到 dataframe。 我嘗試過的是：

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)

但我仍然收到Error ：無法打開 C 中找不到的parsers.pyx文件C:/Users/me/Desktop/Python/Pandas/_libs/parsers.pyx.

誰能告訴我我在這里做錯了什么？

****************** Traceback 為了獲得我實施的 Traceback：

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

我有：

Exception in user code:

我今天遇到了同樣的問題，重新安裝 pandas 和 numpy 沒有幫助。 然后我意識到我的分隔符是錯誤的； 修復解決了這個問題。 值得檢查嗎？

此外，您的回溯使它看起來文件中可能存在損壞； 也許也在這里發布文件的頂部以進行調試。

這是一個老問題，但萬一有人像我一樣用谷歌搜索它。在我的情況下，這是編碼問題 - 盡管正確的編碼是 1251，但文件打開為 utf-8
