title: Problem with determinism : set a buffer size in the CUBLAS_WORKSPACE_CONFIG environmental variable
body: <p>I have problem of non-determinism with a LSTM model and I read that I should set a single buffer size in the CUBLAS_WORKSPACE_CONFIG environmental variable, with:</p>
  <pre><code>    CUBLAS_WORKSPACE_CONFIG=:4096:2
  </code></pre>
  <p>I am using Anaconda 1.9.12 with Python 3.7, and cudaToolkit 11.0.221. I have no clue where to insert that instruction (except that I know it is not in my python code ;-)</p>
  <p>Any indication is most welcome.
  Thanks in advance for your help</p>
