Save summary as image using Linear Models

Question

I am trying to save as PNG File the summary of some regressions that I am doing using the package linearmodels

from linearmodels.iv import IV2SLS
[...]
modelIV =IV2SLS.from_formula(formulaIV,Data).fit(cov_type='unadjusted')
print(modelIV.summary)

I tried to do this, but it is not working:

plt.rc('figure', figsize=(12, 7))
plt.text(0.01, 0.05, str(modelIV.summary()), {'fontsize': 10}, fontproperties = 'monospace')
plt.axis('off')
plt.tight_layout()
plt.savefig('iv_model.png')

Can you help me to figure out what is wrong? Thanks in advance!

What's going wrong? Do you get an error? Or no error but no file? — doctorlove, Nov 10 '21 at 10:43
I get a file but once you open the file it is not readable, some rows are written over others and columns are not in the right place. — Luigi Modica, Nov 10 '21 at 10:49

Do not know why but this is working:

plt.rc('figure', figsize=(12, 7))
plt.text(0.01, 0.05, modelIV, {'fontsize': 10}, fontproperties = 'monospace')
plt.axis('off')
plt.tight_layout()
plt.savefig('iv_logit.png')

summary is a property and so should not be called.

from statsmodels.api import add_constant
from linearmodels.datasets import wage
from linearmodels import IV2SLS
import matplotlib.pyplot as plt

men = wage.load()
men = men[["educ", "wage", "sibs", "exper"]]
men = add_constant(men)
men = men.dropna()

res_first = IV2SLS(men.educ, men[["const", "sibs"]], None, None).fit(
    cov_type="unadjusted"
)

plt.rc("figure", figsize=(12, 7))
plt.text(
    0.01, 0.05, str(res_first.summary), {"fontsize": 10}, fontproperties="monospace"
)
plt.axis("off")
plt.tight_layout()
plt.gcf().tight_layout(pad=1.0)
plt.savefig("iv_model.png", transparent=False)

produces
