可能链接到Cannot call particular java method from Clojure
使用smile包，我已经升级到了3.0.0，但是无法调用一些方法。
现在在REPL中：

(import smile.math.MathEx)

(MathEx/log2 5.)
=> 2.321928094887362
(MathEx/pow2 5.)
Syntax error (IllegalArgumentException) compiling . at (C:\Users\AAlmosni\AppData\Local\Temp\1\form-init13649993705313983821.clj:1:1).
No matching method pow2 found taking 1 args for class smile.math.MathEx
(MathEx/sigmoid 5.)
Syntax error (IllegalArgumentException) compiling . at (C:\Users\AAlmosni\AppData\Local\Temp\1\form-init13649993705313983821.clj:1:1).
No matching method sigmoid found taking 1 args for class smile.math.MathEx
(MathEx/isPower2 32)
=> true

这让我很困惑--有些方法可以正常工作，有些则不行。下面是MathEx.class的摘录：

public static double log2(double x) {
        return Math.log(x) / LOG2;
    }

    public static double log(double x) {
        double y = -690.7755D;
        if (x > 1.0E-300D) {
            y = Math.log(x);
        }

        return y;
    }

    public static double log1pe(double x) {
        double y = x;
        if (x <= 15.0D) {
            y = Math.log1p(Math.exp(x));
        }

        return y;
    }

    public static boolean isInt(float x) {
        return x == (float)Math.floor((double)x) && !Float.isInfinite(x);
    }

    public static boolean isInt(double x) {
        return x == Math.floor(x) && !Double.isInfinite(x);
    }

    public static boolean equals(double a, double b) {
        if (a == b) {
            return true;
        } else {
            double absa = Math.abs(a);
            double absb = Math.abs(b);
            return Math.abs(a - b) <= Math.min(absa, absb) * 2.220446049250313E-16D;
        }
    }

    public static double sigmoid(double x) {
        x = Math.max(-36.0D, Math.min(x, 36.0D));
        return 1.0D / (1.0D + Math.exp(-x));
    }

    public static double pow2(double x) {
        return x * x;
    }

    public static boolean isPower2(int x) {
        return x > 0 && (x & x - 1) == 0;
    }

你知道是什么导致导入失败吗？
谢谢你，
