TypeError: ufunc 'sqrt' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''
 

解决思路

类型错误：ufunc 'sqrt'不支持输入类型，并且不能根据类型转换规则“safe”安全地强制输入任何受支持的类型。

解决方法

根据scatter函数用法，可知，绘图属性，需要在前边加上标志符号！

def scatter(x, y, s=None, c=None, marker=None, cmap=None, norm=None, vmin=None,
            vmax=None, alpha=None, linewidths=None, verts=None, edgecolors=None,
            hold=None, data=None, **kwargs):
    ax = gca()
    # Deprecated: allow callers to override the hold state
    # by passing hold=True|False
    washold = ax._hold

    if hold is not None:
        ax._hold = hold
        from matplotlib.cbook import mplDeprecation
        warnings.warn("The 'hold' keyword argument is deprecated since 2.0.",
                      mplDeprecation)
    try:
        ret = ax.scatter(x, y, s=s, c=c, marker=marker, cmap=cmap, norm=norm,
                         vmin=vmin, vmax=vmax, alpha=alpha,
                         linewidths=linewidths, verts=verts,
                         edgecolors=edgecolors, data=data, **kwargs)
    finally:
        ax._hold = washold
    sci(ret)
    return ret

将

plot.scatter(x,dataRow_i.tolist(), 'r')

改为即可！

plot.scatter(x,dataRow_i.tolist(), c='r')

哈哈，大功告成！
