我该如何解决？看来该系统已变为只读状态。
我尝试使用root用户创建和修改文件，但是也失败了。
答案 0 :(得分：1)
这帮助我解决了该错误：
从无业游民的data = pd.read_csv("data.csv")
maxDecimalPlaces = 0
for index, row in data.iterrows():
# considering you want to evaluate on a column say col_name
decimalPlaces = abs(decimal.Decimal(row["col_name"]).as_tuple().exponent)
if decimalPlaces > maxDecimalPlaces:
maxDecimalPlaces = decimalPlaces
然后退出VM，将其暂停并再次执行sudo fsck -fy /dev/sda1。
