Error when loading bw2data: module 'numpy' has no attribute 'bool' #141

Closed dominikmaierhofer closed 1 year ago

dominikmaierhofer commented 1 year ago

Dear brightway community.

Unfortunately I'm getting an error when importing bw2data (or any other bw2 package). It says that the package 'numpy' has no attribute 'bool'. I already tried deleting and reinstalling the whole bw2 conda environment as well as update bw2 and update numpy. Somehow nothing seems to work.

The issue was raised when I wanted to start analysing a supply chain via Graph Traversal. I installed bw_graph_tools and from there on I always got the error raise.

Any help is very much appreciated. Many thanks in advance.

AttributeError: module 'numpy' has no attribute 'bool'. np.bool was a deprecated alias for the builtin bool. To avoid this error in existing code, use bool by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.bool_ here. The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Update: As suggested here (https://stackoverflow.com/questions/74893742/how-to-solve-attributeerror-module-numpy-has-no-attribute-bool) I downgraded numpy to the version 1.23.1.
