Description

How to Reproduce

The python file (test.py) is:
from mathics.session import MathicsSession
session = MathicsSession(add_builtin=True, catch_interrupt=True)

result = session.evaluate('5!').to_python()
print(result)

$python test.py

I have the same issue

The warnings are shown before or after the evaluation?

What about the output of the following modified script?

test2.py

from mathics.session import MathicsSession
print("Creating the session:\n")
session = MathicsSession(add_builtin=True, catch_interrupt=True)
print(10*"*","\n", "evaluating:")
result_expr = session.evaluate('5!')
print(10*"*","\n", "converting to python:")
result = result_expr.to_python()
print(result)

For me the warnings are shown before the evaluation, at :
session = MathicsSession(add_builtin=True, catch_interrupt=True)

Here's the output of your modified script :

It seems that in your configuration there are problems loading some of the builtin modules. Which version of the code are you using? The current master or some of the releases?

Alexishul · Answer 5 · Thu May 04 2023 20:52:38 GMT+0800 (China Standard Time)

I installed it yesterday from PyPi so i guess i'm using the current master, how can i verify ?

Juan Mauricio Matera · Answer 6 · Thu May 04 2023 20:54:01 GMT+0800 (China Standard Time)

What is the output of

import mathics
mathics.__version__

?

Alexishul · Answer 7 · Thu May 04 2023 21:00:08 GMT+0800 (China Standard Time)

The output of

import mathics
print(mathics.__version__)

is
6.0.1

Juan Mauricio Matera · Answer 8 · Thu May 04 2023 21:55:47 GMT+0800 (China Standard Time)

The issue is related to the way in which the formatters in mathics.format are loaded. If the formatters are not loaded at the right time, some builtin modules can not be properly loaded, which is the reason for the warnings.

#845 partially fixes this, allowing that MathicsSession to be created without problems; hence, the warnings disappear.

I have the same issue. mathics Version 5.0.2 works fine. But error occurs since mathics 6.0

R. Bernstein · Answer 10 · Thu Nov 09 2023 20:41:14 GMT+0800 (China Standard Time)

@rochant try the code in #845 and let us know if this fixes the problem. Thanks.

rochant · Answer 11 · Fri Nov 10 2023 15:38:42 GMT+0800 (China Standard Time)

I confirmed that #845 fixed this problem. Thanks.
