python - 在 datalab 中导入 gcsfs 出现错误

Question

当我在 datalab 中导入 gcsfs 时，import gcsfs我有这个与 fsspec 包相关的无效语法错误。是不是跟版本有关

  File "/usr/local/envs/py3env/lib/python3.5/site-packages/IPython/core/interactiveshell.py", line 2961, in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)

  File "<ipython-input-3-3f25f74e3f1b>", line 1, in <module>
    import gcsfs

  File "/usr/local/envs/py3env/lib/python3.5/site-packages/gcsfs/__init__.py", line 5, in <module>
    from .core import GCSFileSystem

  File "/usr/local/envs/py3env/lib/python3.5/site-packages/gcsfs/core.py", line 7, in <module>
    import fsspec

  File "/usr/local/envs/py3env/lib/python3.5/site-packages/fsspec/__init__.py", line 10, in <module>
    from .mapping import FSMap, get_mapper

    from .core import url_to_fs

  File "/usr/local/envs/py3env/lib/python3.5/site-packages/fsspec/core.py", line 314
    out[0] = (f"{out[0][1]}://", out[0][1], out[0][2])
                              ^

为了扩展 Claros 的答案，潜在的问题是 gcsfs 继承的 fsspec 包。 fsspec 最近的 0.8.0 版本实现了 f-strings，这会导致错误。要修复它，只需安装仍支持 Python 3.5 的最新 fsspec 版本，即

!pip install fsspec==0.6.2

https://pypi.org/project/fsspec/0.6.2/
您可能还需要降级 gcsfs。我得到它的工作

!pip install  --upgrade gcsfs==0.5.3
