Hi,
The _ZN10tensorflow11GetNodeAttrERKNS_9AttrSliceEN4absl14lts_2020_09_2311string_viewEPSs error was caused by a change in ABI in between TF2.5 and TF2.6 not yet reflected in TF-DF.
The last version of TF-DF (v0.1.9; released on 31 August 2021) solves this issue.
Ps: For future reference, such errors can generally be solved by finding and installing the corresponding version of TF and TF-DF :).
