Flow fails in step 3

[rvijgen]

It seems like this worked a few days ago, but now I get this error:

This is most likely a version mismatch issue between openroad and openlane due to recent changes. We'll have to wait for someone to provide a list of working versions, since none of the previous suggestions work, e.g., using openlane 2022.11.12_3_g1298859.

Cross-posting from https://github.com/The-OpenROAD-Project/OpenLane/issues/1953#issuecomment-1691581648:

This turned out to be an easy fix.

In /content/conda-env/share/openlane/scripts/odbpy/reader.py you will need to modify line 37 to be odb.read_def(self.db.getTech(), def_in). Currently, line 37 reads odb.read_def(self.db, def_in).

Issue was fixed for the notebook we were using by fixing the versions to the following:

#@title Install dependencies {display-mode: "form"}
#@markdown - Click the ▷ button to setup the digital design environment based on [conda-eda](https://github.com/hdl/conda-eda).

openlane_version = '2023.07.25_2_g01e67230' #@param {type:"string"}
openroad_version = '2.0_9484_g353633e01' #@param {type:"string"}
open_pdks_version = '1.0.428_2_g405227f' #@param {type:"string"}

if openlane_version == 'latest':
  openlane_version = ''
if open_pdks_version == 'latest':
  open_pdks_version = ''
if openroad_version == 'latest':
  openroad_version = ''
