tf.compat.v1.gfile.Exists
Stay organized with collections

Determines whether a path exists or not.
tf.compat.v1.gfile.Exists(
filename
)
Used in the notebooks
with open("/tmp/x", "w") as f:
f.write("asdf")
4
tf.io.gfile.exists("/tmp/x")
True
You can also specify the URI scheme for selecting a different filesystem:
# for a GCS filesystem path:
# tf.io.gfile.exists("gs://bucket/file")
# for a local filesystem:
with open("/tmp/x", "w") as f:
f.write("asdf")
4
tf.io.gfile.exists("file:///tmp/x")
True
This currently returns True for existing directories but don't rely on this
behavior, especially if you are using cloud filesystems (e.g., GCS, S3,
Hadoop):
tf.io.gfile.exists("/tmp")
True
Returns |
|---|
|
True if the path exists, whether it's a file or a directory.
False if the path does not exist and there are no filesystem errors.

Raises |

errors.OpError

Propagates any errors reported by the FileSystem API.
