Error when re-opening Revit

Hi everybody!
I’m new to pyRevit, so I’d like to apologize if I’m doing this wrong.
I’m trying to create a code to insert the pipe flow rate through a calculation on a shared parameter in the pipe family.
The first time I ran the code it worked fine. However, when I reopened Revit, the code started showing two errors ( I will put their printouts here and the code as well). I don’t know what can be happening. If someone can help, I would be very grateful.

try removing this :point_up:
you don’t seem to use it and it seems to be the issue.

Hi, thanks for responding!
I removed it as you suggested, but now it generates other errors. I tried to make a simple code, but it still gives errors.

#! python3

import sys



CPython Traceback:
AttributeError : ‘ScriptIO’ object has no attribute ‘write’
File “C:\Users\willian.silva\OneDrive - Bild Desenvolvimento Imobiliário Ltda\Área de Trabalho\TCC\TCC.extension\\TCC.panel\Vazão.pushbutton\”, line 5, in

em Python.Runtime.PyScope.Exec(String code, PyDict locals)
em PyRevitLabs.PyRevit.Runtime.CPythonEngine.Execute(ScriptRuntime& runtime)

and without this it works right?

looking at you code, you don’t need to work with cpython / python3, so just remove the first line and that should work accordingly

You really didn’t need it! I removed it, now it’s running. Thank you very much!

But now why can’t I import the numpy ?

I ran a test script, look what happened:

#! python3
# -*- coding: utf-8 -*-

import sys
print('\n## sys.path')

def print_html(output_str):

    import numpy as np
    print('\n numpy array:')
    print(repr(np.arange(15).reshape(3 ,5)))
except Exception as ex:
    print('numpy load error {}'.format(ex))

    import pandas as pd

    df_dict = {'key 1': 1,'key 2': 2, 'key 3': 3}
    df = pd.DataFrame([df_dict])

    print("\n## pandas DataFrame:")
except Exception as ex:
    print(f'pandas load error: {ex}')

Do you know how I can fix it?

you may want to create a new topic to make it easier for others in the forum.
There are a few post about that subject if you look for ‘numpy’


I faced a similar issue:

  1. Make sure I had python 3.8.5 installed
  2. Solution was to set a user environment variable to the pyRevit cpython engine
