Question

Anybody ever seen this before I m running a local agent in a conda env with python 3 8 13 and it s the same one I registered the flow on The unpickling seems to be the issue but I m really confused about the other python version mentioned in this error msg ```Failed to load and execute flow run FlowStorageError An error occurred while unpickling the flow n ModuleNotFoundError No module named snowflake nThis may be due to one of the following version mismatches between the flow build and execution environments n python flow built with 3 8 13 currently running with 3 8 10 nThis also may be due to a missing Python module in your current environment Please ensure you have all required flow dependencies installed ``` I created another flow that logged the environment then ran that one via the UI too It reported that it was running in the right env Where is this 3 8 10 version coming from And what s the solution for the issue of not being able to pull up snowflake I didn t have this issue with my last prefect setup so I m just kinda scratching my head here

But isn t it strange that it s doing this with snowflake

Jacob Bedard · Answer

I installed that one with pip

Jacob Bedard · Answer

Well it s running at the moment I kinda hacked it with an import of the snowflake connector in the task Seems to have gotten beyond that initial issue

Jacob Bedard · Answer

ouch It failed at the import snowflake stage It just can t find snowflake even though I installed it in the normal way

I recommend going through the Discourse thread it includes many options you can try

Anna Geller · Answer

building a package modifying pythonpath adding the path to the agent

Jacob Bedard · Answer

I think that s the part where I m a bit confused

Jacob Bedard · Answer

I read through the doc and I see how it makes sense if you have your own package being used The tricky part for me is that I installed via pip so I thought it would be picked up by prefect Do I have to specify the path in the conda env where the packages are installed

Jacob Bedard · Answer

Oh I m getting closer here ```Exception Version mismatch this is the cffi package version 1 15 0 located in home ubuntu anaconda3 envs prefect env lib python3 8 site packages cffi api py When we import the top level cffi backend extension module we get version 1 14 0 located in usr lib python3 dist packages cffi backend cpython 38 x86 64 linux gnu so The two versions should be equal check your installation ```

Jacob Bedard · Answer

Oh man that was brutal I scoured the internet once I got the new error msg Turns out I needed to uninstall and reinstall prefect

Jacob Bedard · Answer

That fixed my issue It was looking over to some other so config file I was unfamiliar with shown above It wiped the slate clean once I reinstalled prefect I also did the reinstall with conda instead of pip Not sure if that had an impact but I m up and running now slightly smiling face Thanks for the help I wouldn t have gotten to the next error message without it
