DASK : IOError: [Errno 13] Permission denied:

Question

我正在使用 Dask 0.10 和最新的 Anaconda 发行版，我运行在调用 .compute(get=dask.multiprocessing.get) 后出现以下错误：

  File "<ipython-input-8-cd6a1c9a02b6>", line 309, in find_matches
    merged = data.merge(matches, on='url', how='left')

  File "C:\Users\user\AppData\Local\Continuum\Anaconda2\lib\site-packages\dask\dataframe\core.py", line 1664, in merge
    suffixes=suffixes, npartitions=npartitions)

    with open('log', 'a') as f:

IOError: [Errno 13] Permission denied: 'log'

我不知道是什么原因造成的。 Dask需要在根目录下写吗？我在一台 我没有管理员权限但有防火墙 .

的机器上工作

Answer 1

Does Dask needs to write on the root directory?

不，Dask 完全在用户空间内运行，Anaconda 通常也是如此。在提供的回溯中，错误似乎来自尝试打开本地目录中名为 "log" 的文件。也许您是运行来自没有写入权限的地方的 Dask？
