大家好，我一直在尝试将输出图表保存为plt.savefig("coeff.png")svg或 png，但我得到的只是一张空白图片。
无论如何，我可以将我的绘图导出为图片格式吗？
下面是我的代码。
# These are the (standardized) coefficients found
# when it refit using that best alpha
list(zip(X.columns, LGBMR.feature_importances_))
#Now let's make it more presentable in Pandas DataFrame and also in standard form for numbers
df_LGBM_model_coefficients = pd.DataFrame(list(zip(X_train.columns, LGBMR.feature_importances_)))
df_LGBM_model_coefficients.rename(columns={0:'Features', 1: 'Coefficients'}, inplace=True)
df_LGBM_model_coefficients = df_LGBM_model_coefficients.iloc[1:]
df_LGBM_model_coefficients = df_LGBM_model_coefficients.sort_values(by = 'Coefficients', ascending = False)
#only retain the important ones.
df_LGBM_model_coefficients_top_10 = df_LGBM_model_coefficients.head(10)
plt.figure(figsize=(12,12))
sns.set_style('whitegrid')
sns.set(font_scale=0.8)
ax = sns.barplot(x = 'Coefficients',y='Features', data = df_LGBM_model_coefficients_top_10)
ax.set_title("LGBMR …
