Issue: evidently slow in docker
Root cause: Environment Incompatibility

when running in docker it will take more time and running locally, it will create all charts in less time.
**total rows in prediction data - 4000
total rows in reference data 20000
numerical method-ks test, numerical thres-0.6
cat method -chi-square,categorical thres-0.4**
and create 2 charts(data drift,correlation chart) I use a function

```
def detect_features_drift(reference, production, column_mapping, get_scores=False):
    """
    Returns True if Data Drift is detected, else returns False. 
    If get_scores is True, returns scores value (like p-value) for each feature.
    The Data Drift detection depends on the confidence level and the threshold.
    For each individual feature Data Drift is detected with the selected confidence (default value is 0.95).
    """

    data_drift_report = Report(metrics=[DataDriftPreset()])
    # print(production.head())
    data_drift_report.run(reference_data=reference, current_data=production, column_mapping=column_mapping)
    report = data_drift_report.as_dict()

    drifts = []
    num_features = column_mapping.numerical_features if column_mapping.numerical_features else []
    cat_features = column_mapping.categorical_features if column_mapping.categorical_features else []
    # print(production.columns.tolist(),'current')
    # print(report["metrics"][1]["result"]["drift_by_columns"],'report')
    for feature in num_features + cat_features:
        drift_score = report["metrics"][1]["result"]["drift_by_columns"][feature]["drift_score"]
        if get_scores:
            drifts.append((feature, drift_score))
        else:
            drifts.append((feature, report["metrics"][1]["result"]["drift_by_columns"][feature]["drift_detected"]))

    return drifts 
```

in my code and that function is taking lot of time .

Hi @ankita2020 - you seem to be using Evidently version 0.2.7 . The latest version is 0.4.18, and it includes various improvements, including those speeding up drift calculations. We recommend upgrading to this version - let us know if you observe any issues with it.

Hi @elenasamuylova - I used the same version locally, and it still takes less time to generate all the charts. However, running the code in Docker with the same version takes approximately three times longer. If the version were the issue, it should take more time on my local machine as well. Are there any Ubuntu-specific versions required in Docker, or do you have any other suggestions? Ubuntu local version 22.04 and in docker ubuntu version 18
