Attention: this Space need to be duplicated to work</h2>
<p class="main-message">
To make it work, <strong>duplicate the Space</strong> and run it on your own profile using a <strong>private</strong> GPU (T4-small or A10G-small).<br />
A T4 costs <strong>US$0.60/h</strong>, so it should cost < US$1 to train most models.
